Chunking and passage retrieval

Chunking is how retrieval systems split a page into passages, and passage retrieval is how they pick a few of those passages — not the whole page — to build an answer from.

Why it matters

A section is read on its own, without the paragraph above it. Sections that name their subject and state their claim survive chunking; ones that lean on context lose their meaning.

How to see it on your own site

Copy one section into an empty document and read it cold.
