Pros: Better recall when structure preserved. Cons: Tables/code need special handling.
Detailed answer
Pros: Better recall when structure preserved. Cons: Tables/code need special handling. Decision: pick when benefits outweigh operational cost. Core: Chunk by tokens with overlap, headings, or semantic splits. Embedding model maps text to vectors; must match query/doc language. Dimension and MTEB quality matter. Real-time example: Markdown by ## headers; 512-token chunks with 64 overlap; bge/e5 embeddings. Pros: Better recall when structure preserved. Cons: Tables/code need special handling. Common mistakes: Splitting mid-sentence randomly; mixing embedding models in one index. Best practices: Keep embedding model versioned; store metadata (source, date). Audience level: Engineering Manager.
