Before building the index, select a representative document set and test extraction, source identifiers, access rules, updates, and removals. Record failures by document type so the team can fix the pipeline before treating answer quality as a model problem.
Inventory Sources and Authoritative Versions
Record source owner, effective date, allowed users, update method, and intended questions. Exclude superseded or unapproved copies from the initial serving collection.
Validate Extraction on Representative Files
Test headings, tables, scanned pages, footnotes, and policy exceptions before bulk ingestion. Keep the original record and enough location metadata to inspect extraction failures.
A document can appear successfully processed while losing the relationship that makes its content meaningful. In a hypothetical policy table, the text extractor might retain every amount and label but separate the values from the conditions they describe. A search result containing the correct words could then support the wrong answer. Compare selected extracted passages with the original page, especially where tables, footnotes, and exceptions carry the rule. Keep extraction defects separate from retrieval tuning so the team does not try to repair damaged source content by changing the model.
Design Updates, Permissions, and Removals
Specify how change signals trigger processing and what happens after a missed update. Test serving-index removal separately from any retention duty for the original record.
Example: Withdraw a test policy, replace it with a new version, and confirm that the assistant no longer cites the withdrawn version for current guidance.
Use Questions to Verify the Pipeline
Maintain a small task set tied to expected source versions and passages. Inspect ingestion and retrieval evidence before attributing every weak answer to the model.
Discuss the implementation scope with Sprinklenet. A useful starting point: a source-readiness and update-path review before RAG implementation.
