RAG Knowledge Base Development for Business Documents

We turn the documents a business already owns into a searchable base that answers questions with the source attached. Contracts, standard procedures, product documentation and internal policy are indexed together, and every answer points back to the passage it came from.

Cited Answers Document Governance Access Control
  • Answers linked to the document and section they came from
  • Permissions follow the document, not the interface
  • Content updates are versioned rather than overwritten

What Goes Into the Knowledge Base

The base is only useful if the material inside it is current, owned and permitted. These five categories cover most requirements.

Standard Procedures

Operating steps, checklists and escalation paths, indexed by process name and by the situation they apply to.

Product and Service Documentation

Specifications, setup guides and pricing rules that staff and customers both ask about.

Contracts and Terms

Agreement templates, delivery terms and warranty conditions, answerable by clause rather than by whole document.

Internal Policy

Approval limits, expense rules, leave policy and compliance requirements, each with an owner and a review date.

Support History

Resolved questions and case notes, included where they add a worked example the policy documents do not cover.

Ownership Records

For every document: who owns it, when it was last reviewed and which teams may retrieve it.

Retrieval

How a Question Becomes an Answer

Four steps, in this order. Skipping the first two is what makes a knowledge base answer confidently and wrongly.

1. Parse

Documents split into passages with their headings and page references kept, so a retrieved answer can be traced back.

2. Index

Passages indexed for retrieval, with document metadata attached: owner, department, effective date, permission level.

3. Retrieve

A question returns the passages that match it, filtered first by the permission level of the person asking.

4. Answer with Source

The response quotes the passage and names the document and section. Where nothing relevant is found, it says so instead of guessing.

Questions

Common Questions

How much document material is needed before starting?

Enough to cover the questions the base is expected to answer. Where a topic has only one outdated document, that topic is scoped as a content task first rather than an indexing task.

Can the answer be traced back to the source?

Yes. Each answer names the document and section it came from, and the passage is shown alongside the response so it can be checked.

What happens when a document is updated?

The new version replaces the indexed passages and the effective date changes. Older passages stop being retrieved, so answers do not mix two versions of the same policy.

Can different teams see different material?

Yes. Permission levels are attached to documents and applied during retrieval, so a shared base can serve several teams with different access.

That combination shows what can be answered from existing material and where the documentation needs work first.
