synthesis of retrieval chunking studies in enterprise corpora

Recent retrieval literature and field evaluations show chunk size and boundary strategy strongly affect both grounding precision and response latency (arXiv).

evidence map

• Smaller chunks improve precision but can hurt recall.
• Semantic boundary chunking outperforms fixed windows in mixed documents.
• Metadata enriched chunks reduce retrieval ambiguity.

method boundary

No single chunking policy dominates across all corpus types. Policy must follow document structure and query distribution.

my take

Chunking is one of the highest leverage and most underinstrumented parts of retrieval quality.
