The Knowledge Problem

Every organization has a knowledge problem. Critical information is scattered across SharePoint sites, email threads, PDF manuals, Confluence pages, and the heads of long-tenured employees. Finding the right answer to an operational question often takes longer than acting on it.

Traditional search returns documents, not answers. An employee searching for "what is our return policy for enterprise clients" gets a list of 47 documents, some outdated, some irrelevant. They must read, compare, and synthesize — or just ask a colleague and hope the answer is current.

What Is Retrieval-Augmented Generation?

Retrieval-Augmented Generation (RAG) combines two capabilities: retrieval (finding the most relevant documents or passages from your knowledge base) and generation (using a large language model to synthesize a natural-language answer from those passages).

RAG gives the model passages from your documents to use as evidence. An answer can still be wrong if retrieval misses the right passage or the model misreads it. Provide citations and check consequential answers against the source. According to Microsoft's Azure AI Search documentation, RAG is the recommended pattern for enterprise Q&A over proprietary data.

Trace a return-policy answer back to its source

  1. Index

    Make approved policy passages searchable

    Split the policy documents into passages and store source references and version details with them.

    Indexed passage

    Reference
    Sample enterprise returns policy · v2 · §2
    Passage
    Find the return deadline for an enterprise order in its purchase agreement.

  2. Retrieve

    Find evidence for the question

    For an enterprise return question, combine exact terms with semantic matches and retrieve passages the requester is allowed to see.

    Retrieval result

    Question
    Where can I find the return deadline for this enterprise order?
    Matched passage
    Sample enterprise returns policy · v2 · §2

  3. Ground

    Draft the answer from those passages

    Give the model the retrieved passages with their source references. Ask it to cite the policy that supports each material claim.

    Draft with citation

    Answer
    Check this order’s purchase agreement for the return deadline.
    Citation
    Sample enterprise returns policy · v2 · §2

  4. Check

    Open the citation and verify the rule

    Check that the cited policy is current and covers the requester’s case. If the evidence is missing or contradictory, flag the gap for review.

    Evidence check

    Supported
    The cited passage points to the purchase agreement.
    Still needed
    Open the agreement to verify the actual deadline.
