Starting from a compliance incident caused by a split paragraph, the author walks through fixed-size chunking, sentence windows, hierarchical chunking, and semantic chunking — explaining when each works and when it fails. Special attention is given to enterprise document types: PDFs with complex layouts, tables (converted to natural-language sentences for better retrieval), and slide decks with diagrams. A routing framework selects the right parser per document type. RAGAS metrics (context recall, faithfulness, context precision) are used throughout to quantify improvements, with context recall jumping from 0.72 to 0.88 after switching to sentence windows for narrative documents. ## Full article daily.dev links to this article rather than hosting it.
