Why preserve document structure and parent-child relationships in RAG?

Uses hierarchy and adjacency to recover context that flat chunks lose while avoiding indiscriminate document expansion.

TL;DR

I preserve document, section, parent, and source-offset metadata so a retrieved passage can be interpreted in its original scope. The search unit can remain small for precision while the application expands to a parent or neighboring passage when needed. This is especially useful for procedures, policies with exceptions, and documents whose headings carry meaning.

Overview
A flat passage often loses the heading, scope, exception, or preceding definition that gives it meaning.

Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
If a child chunk says requests are retained for thirty days, its parent heading may reveal that the rule applies only to audit exports. Returning the whole document would add noise, so I expand selectively and deduplicate overlapping parents. Evaluation includes questions where the answer depends on a heading, a preceding definition, or a nearby exception.
