- PDF text extraction, not chunking, is the usual root cause of bad retrieval on documents finding
- Chunk identifiers must be deterministic or re-indexing duplicates the whole corpus finding
- Prepending document-level context to each chunk before embedding reduces retrieval failures finding
- Post-filtering an approximate nearest neighbour search can return far fewer than k results finding
- Position in the context window changes how well a model uses a retrieved passage finding
- Retrieve wide and rerank narrow, because a bi-encoder cannot see the query and document together finding
- Hybrid search results need rank fusion because BM25 and vector scores are not comparable finding
- Retrieval and generation must be evaluated separately or you tune the wrong component finding
- Empty and whitespace-only text still produces a confident embedding that pollutes an index finding
- Embedding APIs reject input over the token limit rather than truncating it finding
- Asymmetric embedding models need their query and passage prefixes or recall collapses finding
- LangChain's character text splitters count characters, while embedding limits are in tokens finding
