Sparse Vectors and Hybrid Search - Qdrant | CodeMentor

1What is a sparse vector, and how does it differ structurally from the dense vectors used in semantic search?ExpertHigh

2Why would you combine dense and sparse vector search instead of relying on dense embeddings alone?ExpertHigh

3What is the IDF modifier on a sparse vector configuration, and what problem does it address?ExpertHigh

4How would you build a hybrid search query that retrieves candidates from both a dense embedding and a BM25-style sparse vector, then fuses the results?ExpertHigh

5What are the tradeoffs of hybrid search in terms of indexing cost, storage, and query latency compared to dense-only search?ExpertHigh
