Passage Retrieval
Passage retrieval selects and ranks text passages or chunks as the retrieval unit instead of returning only whole documents.
What it means
Passages may be natural sections or mechanically sized chunks linked back to a source document. Their boundaries, overlap, metadata and context determine whether a returned unit remains interpretable.
Why it matters
Smaller units can isolate evidence and fit limited context windows, but they can sever definitions, exceptions or provenance. Passage recall and document usefulness therefore need separate checks.
Example
A dense retriever returns the two paragraphs defining refund eligibility, with the policy title, effective date and URL retained for context and citation.
Common mistakes
Do not chunk by character count without structural review, detach exceptions from rules or lose the canonical source. Measure boundary failures and duplicate overlap.
How AYSA handles this
Signals reviewed
rendered headings, section boundaries, chunk metadata, canonical URL, effective date
Problem AYSA can identify
AYSA can flag web sections likely to lose their definition, exception or provenance when retrieved alone.
Recommendation prepared
The proposal improves headings, local context and source metadata without padding the page.
Approval preview
The user reviews the isolated passage, missing dependency and exact proposed source edit.
Execution
AYSA can apply approved WordPress structure and context changes while preserving the canonical URL.
Verification
AYSA recrawls the section and, when connected, confirms the retrieved passage retains required context.
Limits
AYSA cannot choose chunk boundaries inside an external platform without configuration access.

Frequently asked questions
Is a passage always the same as a fixed-size chunk?
