Parent-child retrieval

Indexing small child passages while returning a larger parent document around the match. It balances match precision and context, but the parent may exceed the generator’s usable budget.

Retrieval engineering

How pages become chunks, vectors and candidates inside an answer engine, and why being retrieved is not being cited.
