RAG and Grocery Store Websites: What Retailers Need to Know
Updated: Sep 3
A customer asks an AI-powered search experience:
“Which grocery store near me has fresh seafood, curbside pickup, and is open after 9 PM?”
Answering that question accurately can require information that changes frequently.
The system may need to determine:
Which grocery stores are nearby
Which locations have seafood departments
Which locations offer curbside pickup
Current operating hours
Whether the information is still accurate
A language model's preexisting knowledge alone may not be enough.
Instead, some AI systems can retrieve relevant, current information and use it when generating a response.
One important technique behind this process is known as:
Retrieval-Augmented Generation
or:
RAG.
RAG matters for grocery retailers because grocery information is unusually:
Local
Store-specific
Dynamic
Product-oriented
and:
Time-sensitive.
Google now explicitly describes RAG—also called grounding—as one of the techniques used in its generative Search experiences: relevant, up-to-date webpages can be retrieved from Google's Search index and used to help generate responses with supporting links.
For grocery retailers, the lesson is not that they need to “install RAG” on their websites.
It is much simpler:
If AI systems retrieve information from the web to answer grocery questions, your website should make accurate grocery information exceptionally easy to discover, retrieve, understand, and verify.
That is where RAG intersects with modern grocery website strategy.

Final Thoughts
What Is RAG?
RAG stands for Retrieval-Augmented Generation.
At a high level, RAG combines two processes:
Retrieval
Find information relevant to a user's question.
Generation
Use that information as context when generating an answer.
The basic concept can be represented as:
User Question
↓
Retrieve Relevant Information
↓
Provide Retrieved Information to the Model
↓
Generate a Grounded Response
Instead of relying entirely on information already represented within the model, retrieval gives the system additional information relevant to the current question.
Why Is It Called “Augmented” Generation?
Because the model's generation process is being augmented with retrieved information.
Imagine asking:
“What time does FreshTown Downtown close tonight?”
A model might know that FreshTown is a grocery retailer.
But store hours can change.
Retrieval could provide current information from a relevant source before the response is generated.
That makes retrieval particularly important for dynamic businesses such as grocery stores.
RAG Explained With a Grocery Example
Suppose a shopper asks:
“Which FreshTown location has a seafood department and grocery pickup?”
A simplified RAG-style workflow might look like this.
Step 1: Understand the Question
Important concepts include:
Brand: FreshTown
Entity Type: Store location
Department: Seafood
Service: Grocery pickup
Step 2: Retrieve Relevant Information
Potential sources might include:
FreshTown Locations
Downtown Location
Northside Location
Seafood Department
Pickup Information
Step 3: Identify Relevant Facts
Suppose the retrieved information establishes:
Downtown → Seafood → Yes
Downtown → Pickup → Yes
Northside → Seafood → No
Northside → Pickup → Yes
Step 4: Generate the Answer
The system can now potentially answer:
FreshTown Downtown offers both a seafood department and grocery pickup.
The retrieval step provides the grounding information used to construct the answer.
Why RAG Matters for Grocery Retailers
Grocery stores have several characteristics that make retrieval particularly relevant.
Grocery Information Changes
Store hours change.
Products change.
Promotions change.
Services change.
Departments change.
Grocery Information Is Local
A shopper usually cares about a particular physical location.
Grocery Information Varies by Store
One location may have seafood while another does not.
Grocery Questions Combine Attributes
Customers do not always ask:
“Where is a grocery store?”
They may ask:
“Which grocery store near me has a butcher, sells halal meat, offers pickup, and stays open late?”
Answering that requires connecting several pieces of information.
RAG Can Help Ground Dynamic Answers
This is one reason retrieval-based AI is particularly relevant to grocery retail.
The AI system does not necessarily need to permanently “know” every store attribute.
It can retrieve relevant current information when the question is asked.
RAG vs a Language Model's Existing Knowledge
This distinction is fundamental.
Model Knowledge
Information represented within the model from its development process.
Retrieved Knowledge
Information retrieved from external sources when answering a question.
For grocery retailers, retrieved knowledge can be particularly valuable for current business information.
Example
A model might broadly know:
Supermarkets commonly have bakery departments.
That does not establish:
FreshTown Westside currently has a Bakery Department.
The second statement is a store-specific fact.
It should come from reliable current information.
Do Not Optimize Around “Training the LLM”
Grocery retailers sometimes frame AI optimization as:
“How do we teach ChatGPT about our store?”
That is usually the wrong operational mindset.
A more useful question is:
“How do we make accurate information about our store easy for search and retrieval systems to access when needed?”
That leads to far more practical improvements.
RAG vs Search
RAG and search are related but not identical.
Traditional search often follows:
Query
↓
Ranked Search Results
↓
User Selects Page
A RAG-style experience can add another layer:
Question
↓
Retrieve Relevant Sources
↓
Extract Relevant Information
↓
Provide Context to Model
↓
Generate Response
↓
Show Supporting Sources Where Applicable
Search retrieves documents.
RAG can use retrieved information as context for generation.
Google Search Provides a Real-World Example
Google's 2026 generative AI guidance explicitly says its AI Search features can use RAG to retrieve relevant, up-to-date webpages from the Search index. Google says its systems then review specific information from those pages to produce more reliable responses with relevant links.
That gives website owners an important practical takeaway:
Traditional search visibility and AI retrieval are increasingly interconnected.
RAG vs LLM Retrieval Optimization
These concepts are closely related but should remain distinct.
RAG
A technical approach used by an AI system:
Retrieve information → provide context → generate answer
LLM Retrieval Optimization
A website strategy:
Make the right information easier for retrieval-enabled systems to find and use.
The grocery retailer generally controls the second—not the first.
You Don't Control the RAG Pipeline
A grocery store cannot tell an external AI platform:
“Retrieve this exact paragraph whenever someone asks about seafood.”
But the retailer can control whether its seafood information is:
Public
Crawlable
Well organized
Specific
Current
Internally linked
Associated with the correct location
That is the practical optimization opportunity.
How an AI System Could Retrieve Grocery Information
Consider:
“Where can I buy a custom birthday cake near Downtown Phoenix?”
Relevant retrieval targets might include:
Grocery location pages
Bakery pages
Custom cake pages
Local business information
Product or ordering pages
Other relevant web sources
The system may then evaluate which information best addresses the query.
The Website Should Provide Clear Retrieval Targets
Instead of putting all grocery information on one enormous homepage, create useful pages for meaningful entities and customer needs.
For example:
Locations
→ Downtown→ Northside→ Westside
Departments
→ Bakery→ Meat→ Seafood
Services
→ Grocery Delivery→ Pickup→ Custom Cakes
This creates clearer retrieval targets.
Query Fan-Out and Complex Grocery Questions
RAG becomes particularly interesting when combined with query fan-out.
Google says its generative AI Search systems may generate multiple related queries to retrieve additional information needed to address a user's original question.
Consider:
“What's the best grocery store near me for fresh seafood, organic produce, and curbside pickup?”
A system might need information corresponding to several subtopics:
Nearby grocery stores
Seafood departments
Organic produce
Curbside pickup
and potentially other attributes.
Grocery Queries Are Naturally Multi-Dimensional
This makes comprehensive grocery information particularly valuable.
A retailer should not create a separate page for every imaginable fan-out query.
Google specifically warns against producing excessive pages for query variations merely to manipulate generative search; its systems can understand related meanings without exact-match pages.
Instead, create strong pages that cover real customer needs comprehensively.
1. Why Grocery Location Pages Matter
Location pages can serve as primary retrieval targets for store-specific questions.
Each physical store should generally have a dedicated page.
A strong location page can include:
Store name
Address
Phone
Hours
Departments
Services
Ordering
Weekly ad
Store-specific features
FAQs
Directions
Consolidate Store-Level Facts
Suppose the question is:
“Does FreshTown Downtown have seafood and delivery?”
The ideal Downtown page should make both facts easy to determine.
Do not force the system—or the customer—to visit six pages to understand the basic store.
2. Why Department Pages Matter
Department pages can become retrieval targets for more specific questions.
Examples:
Bakery
Meat
Seafood
Produce
Deli
A useful Seafood page might explain:
What the department offers
Which locations have seafood
Specialty offerings
Relevant services
Department expertise
Related educational content
Connect Departments to Stores
Explicitly say:
Our Seafood Department is available at the Downtown and Westside locations.
Then link those locations.
This creates a much clearer information network.
3. Why Service Information Matters
Services often determine which store satisfies a customer's question.
Examples:
Grocery pickup
Delivery
Catering
Custom cakes
Special orders
Pharmacy
Do not leave service availability ambiguous.
Example
Weak:
Pickup available.
Better:
Curbside grocery pickup is available at FreshTown Downtown and FreshTown Northside.
Now the service is connected to specific stores.
4. Why Product and Specialty Information Matters
Customers may ask highly specific questions:
“Which grocery store near me sells halal meat?”
“Where can I find Korean groceries?”
“Who carries local produce?”
These questions require more than generic store information.
Build Meaningful Relationships
For example:
FreshTown Downtown
↓
Meat Department
↓
Halal Meat
or:
International Market
↓
International Foods
↓
Korean Grocery Selection
These relationships should reflect actual offerings.
5. Why Weekly Ads Are a RAG Challenge
Weekly ads are one of the most dynamic parts of a grocery website.
They contain information such as:
Product
Price
Promotion
Effective dates
Participating stores
That information may change every week.
A PDF Alone May Not Be Ideal
Suppose the weekly ad is available only as an image-heavy PDF.
Customers can open it.
But important relationships may be less clearly represented than if the website also provides accessible information such as:
Weekly Ad: August 26–September 1, 2026
Participating Locations: Downtown, Northside
Featured Offers:
Ribeye Steak — $9.99/lb
Strawberries — $2.99
Avocados — 3 for $5
The webpage creates additional structured context around the ad.
Do Not Create Thousands of Thin Deal Pages
The answer is not to create an SEO page for every weekly special.
Instead, create a strong weekly-ad experience with useful accessible context.
6. Why Freshness Matters
RAG is particularly valuable when information changes.
But retrieval of outdated information can still produce an outdated answer.
That means retailers need to maintain the source.
High-Priority Grocery Information
Review frequently:
Store Hours
Holiday Hours
Locations
Departments
Services
Ordering
Weekly Ads
Promotions
Product Availability
Date Time-Sensitive Information
Prefer:
Labor Day 2026 Store Hours
over:
Holiday Hours
Prefer:
Weekly Ad: August 26–September 1, 2026
over:
Current Ad
Explicit dates reduce ambiguity.
7. Make Important Information Available as Text
Google's AI-search guidance specifically recommends making important content available in textual form.
That is particularly relevant to grocery websites.
Important information is frequently trapped inside:
Weekly-ad graphics
Store maps
Promotional banners
Images
Interactive widgets
Visuals Should Support the Information
A store can absolutely use attractive graphics.
But important facts should also exist in readable text.
For example:
Seafood Department Available
should not exist only as text embedded in an image.
The page should say it too.
8. Build Strong Entity Relationships
Retrieval is more useful when information has a clear subject.
Compare:
Delivery available.
with:
FreshTown Downtown offers grocery delivery.
The second statement connects:
Location
→ Service
That relationship matters.
Build a Grocery Entity Network
A useful model is:
Brand
↓
Locations
↓
Departments
↓
Services / Products / Specialties
For example:
FreshTown
→ Downtown
→ Bakery
→ Custom Cakes
This reduces ambiguity when relevant information is retrieved.
9. Use Internal Linking to Improve Discovery
Internal links create discovery paths.
For example:
Downtown Location
→ Seafood Department
→ Seafood Guide
or:
Bakery
→ Custom Cakes
→ Downtown Location
Internal linking helps connect information across the website.
Avoid Orphan Pages
An excellent:
Custom Cake Ordering
page provides limited value if no meaningful page links to it.
Connect important pages through:
Navigation
Hubs
Contextual links
Breadcrumbs
10. Structured Data and RAG
Structured data can make certain page information machine-readable.
Useful grocery types can include:
Organization
GroceryStore
LocalBusiness
BreadcrumbList
Product
Offer
Article
Recipe
However:
Structured data is not a RAG switch.
Google explicitly says structured data is not required for its generative AI search and that there is no special schema.org markup needed specifically for generative AI visibility.
Use Schema for What It Actually Does
Structured data can help describe:
This is the Organization.
This is a GroceryStore.
This is a Product.
This is an Article.
That can support a clearer technical foundation.
It does not instruct an external AI system to retrieve the page.
11. RAG and Local Grocery Information
Local information is especially important for grocery retrieval.
A question such as:
“Where can I buy fresh seafood near me?”
requires both:
Offering relevance
and:
Geographic relevance.
Google specifically recommends maintaining accurate Business Profile information for generative search and notes that local business information can appear in generative responses.
Keep Location Information Consistent
Maintain accurate:
Business name
Address
Phone
Hours
Location URL
Business category
across relevant first-party and local-business systems.
12. RAG and Multi-Location Grocery Stores
RAG becomes more complicated when one grocery brand operates multiple locations.
Suppose:
Store | Seafood | Bakery | Delivery | Pickup |
Downtown | Yes | Yes | Yes | Yes |
Northside | No | Yes | Yes | Yes |
Westside | Yes | No | No | Yes |
Now ask:
“Which FreshTown location has seafood and delivery?”
Only:
Downtown
matches both attributes.
Your Website Needs to Preserve These Differences
A generic corporate page saying:
FreshTown offers seafood, bakery, delivery, and pickup.
does not establish which stores offer which features.
Store-specific information is much more useful.
13. RAG and Grocery Ecommerce
RAG also has implications for grocery product discovery.
A shopper might ask:
“Where can I buy Brand X olive oil near me?”
Potentially relevant information includes:
Product name
Brand
Price
Availability
Store
Location
Accurate product information becomes increasingly valuable.
Product Data Needs to Stay Current
Grocery catalogs are challenging because:
Prices change
Inventory changes
Promotions expire
Store availability varies
Do not publish structured product information that cannot be maintained accurately.
14. RAG and Original Grocery Expertise
RAG is not limited to business facts.
It can also retrieve educational content.
For example:
“How do I choose a ripe watermelon?”
A grocery retailer's Produce Department could publish an original guide based on real produce expertise.
Google's current generative-search guidance specifically emphasizes unique, non-commodity, experience-based content over generic information that could come from anywhere.
Grocery Retailers Have Underused Expertise
Potential sources include:
Butchers
Produce managers
Seafood specialists
Bakery teams
Buyers
Store managers
Real operational knowledge can create more differentiated content than generic AI-generated articles.
15. RAG and Citations
Retrieval and citation are connected.
A simplified progression is:
Content Exists
↓
Content Is Accessible
↓
Content Is Retrieved
↓
Content Is Relevant
↓
Content Supports the Answer
↓
Source May Be Cited
Retrieval comes before potential citation.
Retrieval Does Not Guarantee Citation
An AI system may retrieve multiple sources.
Not every retrieved source necessarily appears in the final answer.
That is why retailers should distinguish:
Retrieval Optimization
Make information easier to find.
Citation Optimization
Make information stronger as supporting source material.
Both can be useful.
16. RAG and Google AI Search
Google provides the clearest current search-engine example of RAG relevant to grocery retailers.
Its 2026 guidance says generative Search can use its core Search ranking systems to retrieve relevant, current webpages from the Search index, then use information from those pages to generate grounded responses. Google also describes query fan-out as a technique for gathering information across related subqueries.
For a webpage to be eligible as a supporting link in Google's AI Overviews or AI Mode, it needs to be indexed and eligible to appear in Google Search with a snippet; Google says there are no additional AI-specific technical requirements.
This Reinforces SEO
The practical implication is significant:
Google AI optimization does not replace Google SEO.
Google explicitly says its traditional SEO best practices remain foundational to generative Search.
For grocery stores, that means continuing to prioritize:
Crawlability
Indexability
Internal linking
Useful content
Local information
Ecommerce data
Page experience
Images and video
Structured data where appropriate
17. RAG and ChatGPT Search
ChatGPT Search can also retrieve current web information when answering questions.
For grocery retailers, the practical website strategy remains similar:
Make public information accessible.
Clearly identify the business.
Create strong location pages.
Document departments and services.
Publish useful first-party information.
Maintain freshness.
The exact retrieval and ranking systems differ among platforms, so retailers should avoid assuming Google's RAG implementation describes every AI assistant.
Do Not Build for One Proprietary Pipeline
The durable strategy is to make the website:
discoverable
understandable
accurate
specific
authoritative
and:
current.
Those characteristics are useful across traditional search and multiple AI-assisted experiences.
18. RAG vs GEO, AEO & LLM Optimization
These terms describe different parts of the broader AI-search environment.
RAG
The AI system retrieves external information and uses it to support generation.
Retrieval Optimization
Makes relevant grocery information easier to retrieve.
LLM Optimization
Improves the broader clarity, accessibility, relationships, and usefulness of grocery information for language-model-powered experiences.
AEO
Makes information easier to use in direct answers.
GEO
Addresses broader visibility in generative-search experiences.
Citation Optimization
Makes retrieved information stronger as supporting source material.
A Useful Grocery AI Framework
Think of the process as:
SEO
↓
Discovery
↓
Retrieval
↓
Entity Understanding
↓
Grounding
↓
Answer Generation
↓
Potential Citation
↓
Customer Action
A grocery retailer cannot control every step.
But it can significantly improve the information entering the process.
Does Your Grocery Store Need to Build Its Own RAG System?
For most independent grocery stores:
No.
This is an important distinction.
A grocery retailer does not need to build a custom vector database and RAG infrastructure merely to improve visibility in external AI search products.
The retailer does not control those external retrieval systems.
Website Optimization Comes First
If the goal is:
“Help customers find our grocery store through AI search.”
focus first on:
Website quality
SEO
Local SEO
Information architecture
Locations
Departments
Services
Products
Entity clarity
Authority
Freshness
Building your own RAG application is a separate business decision.
When a Grocery Retailer Might Actually Use RAG
RAG can also be used inside a retailer's own AI applications.
This is different from optimizing for Google or ChatGPT.
Imagine a grocery website assistant where a customer asks:
“Does the Downtown store have gluten-free pasta?”
A retailer-controlled RAG system could potentially retrieve information from its own:
Product catalog
Store database
Department information
FAQs
Policies
Recipes
Weekly specials
and use that information to answer.
Other Potential Grocery RAG Applications
Product Assistant
“What pasta sauces are under $5?”
Store Assistant
“Which location has a pharmacy?”
Recipe Assistant
“What can I make with chicken thighs and avocados?”
Weekly Ad Assistant
“What's on sale for dinner this week?”
Customer-Service Assistant
“How does curbside pickup work?”
Employee Knowledge Assistant
“What's our process for special cake orders?”
These are actual retailer-owned RAG use cases.
Public AI Visibility vs Internal RAG
Keep the two concepts separate.
External AI Search
You optimize your website so third-party systems can discover and use public information.
Retailer-Owned RAG
You build your own system that retrieves information from data sources you control.
Those are very different projects.
Common Grocery Website Problems for Retrieval
Store Information Only on the Homepage
Individual stores lack strong retrieval targets.
Generic Location Pages
Stores cannot be distinguished.
Departments Aren't Connected to Locations
The system cannot determine where an offering exists.
Services Are Chain-Wide but Actually Vary
Information becomes misleading.
Weekly Ads Are Image-Only
Important promotional facts have limited textual context.
Stale Hours
Retrieved information can be wrong.
Orphan Pages
Important content has weak discovery paths.
Generic Marketing Copy
Few concrete facts are available.
Duplicate Location Pages
Retrieval candidates become unnecessarily similar.
Important Content Hidden Behind Interaction
Essential information is unnecessarily difficult to access.
Weak Entity Naming
The same store is described inconsistently.
Product Data Is Stale
Prices or availability cannot be trusted.
RAG Myths Grocery Retailers Should Avoid
Myth #1: “My Grocery Website Needs RAG Software to Appear in AI Search”
No.
External AI platforms control their own retrieval infrastructure.
Myth #2: “RAG Replaces SEO”
No.
Google explicitly connects its RAG-based generative Search retrieval to its core Search systems.
Myth #3: “I Need to Write Tiny AI Chunks”
No.
Google specifically says there is no requirement to break content into tiny chunks for its generative Search systems.
Myth #4: “I Need Special RAG Schema”
No universal RAG-specific Schema.org markup exists for grocery visibility.
Myth #5: “llms.txt Makes RAG Retrieve My Website”
Not for Google Search. Google says it does not use llms.txt for Search visibility or rankings.
Myth #6: “More Pages Mean More RAG Visibility”
Not necessarily.
Google warns against mass-producing query-variation content without added value.
Myth #7: “If My Page Is Retrieved, It Will Be Cited”
Not necessarily.
Retrieval and final source selection are different stages.
Myth #8: “RAG Means AI Always Has Current Information”
No.
Retrieved information can still be outdated, incomplete, or incorrect if the underlying sources are poor.
Myth #9: “Schema Guarantees Retrieval”
No.
Myth #10: “RAG Makes Entity Clarity Unnecessary”
The opposite.
Retrieved information is more useful when it clearly identifies the correct brand, location, department, service, or product.

Frequently Asked Questions
What does RAG mean?
RAG stands for Retrieval-Augmented Generation. It describes a technique where relevant external information is retrieved and provided as context to help an AI system generate a more grounded response.
What does RAG have to do with grocery stores?
Grocery information is often local, store-specific, and frequently changing. Retrieval can help AI systems access current information about locations, departments, services, products, hours, and other grocery attributes.
Does Google use RAG?
Google's 2026 generative Search guidance explicitly identifies retrieval-augmented generation, or grounding, as a technique used to retrieve relevant, up-to-date webpages from its Search index when generating certain AI-search responses.
Does my grocery website need RAG?
Not simply to appear in external AI search.
Google, ChatGPT, and other platforms control their own retrieval systems.
Your job is primarily to make public grocery information accessible, useful, accurate, and easy to understand.
Should a grocery retailer build its own RAG system?
Only if there is a useful business application.
Potential examples include a product assistant, recipe assistant, store-information chatbot, employee knowledge assistant, or weekly-ad assistant.
Is RAG the same as search?
No.
Search retrieves relevant information. RAG uses retrieved information as context for generating an answer.
Is RAG the same as LLM retrieval optimization?
No.
RAG describes an AI-system architecture or technique.
LLM retrieval optimization describes steps website owners can take to make their information easier for retrieval-enabled systems to find and use.
Is RAG the same as GEO?
No.
GEO is a broader optimization concept around generative-search visibility.
RAG is a technical retrieval-and-generation approach that some generative systems use.
Does RAG replace SEO?
No.
For Google specifically, generative Search retrieval builds on its core Search systems, and Google continues to recommend foundational SEO practices.
Do grocery stores need special RAG schema?
No universal RAG-specific Schema.org markup is required.
Should I break every page into tiny chunks for RAG?
No.
Google explicitly says websites do not need to break content into tiny pieces for generative AI Search. Content should primarily be organized for readers.
Does llms.txt improve RAG visibility?
It should not be treated as a universal retrieval mechanism. Google specifically says llms.txt neither improves nor harms visibility or rankings in Google Search.
Why are location pages important for RAG?
They provide clear retrieval targets for questions involving individual stores, addresses, hours, departments, services, and other location-specific attributes.
Why are department pages important?
They help establish what a department offers and which physical locations provide it.
Are weekly ads important for RAG?
Potentially. Weekly ads contain highly current product, price, date, and location information. Providing useful textual context alongside visual ads can make the information clearer and more accessible.
Can RAG guarantee that an AI assistant recommends my grocery store?
No.
Retrieval only provides information for consideration. It does not guarantee a ranking, citation, mention, or recommendation.
What is the most important thing retailers should understand about RAG?
You usually do not need to optimize the AI model.
You need to optimize the information the model may retrieve.
Final Thoughts
RAG and grocery store websites sound like an extremely technical combination.
For most retailers, the practical lesson is surprisingly simple.
Imagine an AI system receives this question:
“Which FreshTown location has seafood, delivery, and is open after 9 PM?”
To provide a useful answer, the system may need to retrieve several facts:
Brand
→ FreshTown
Location
→ Downtown
Department
→ Seafood
Service
→ Delivery
Hours
→ Open until 10 PM
Those facts need to exist somewhere.
More importantly, they need to be:
Accessible
↓
Discoverable
↓
Retrievable
↓
Current
↓
Connected to the correct entities
↓
Clear enough to use
That is the retailer's opportunity.
You do not need a special:
RAG file
RAG schema
AI version of the website
or:
RAG-optimized writing format.
Instead, build a better grocery information system.
Create strong location pages.
Document departments.
Connect services to participating stores.
Publish accurate product and specialty information.
Make important facts available as text.
Build logical internal links.
Use structured data appropriately.
Publish original expertise.
Keep dynamic information current.
Maintain accurate local-business information.
Those practices improve the website for customers while simultaneously creating a stronger information environment for search and retrieval-based AI systems.
RAG may be happening behind the scenes.
The grocery retailer's job is to make sure that when a retrieval system comes looking for an answer, the right answer is actually there.
