Dense vector search (k-NN) is powerful but requires embedding both documents and queries with a neural model at query time. Neural sparse search takes a different approach: expand tokens with learned weights at index time, store them as a rank_features field, and at query time do a fast lookup rather than a vector computation. The result is semantic search with no GPU requirement at query time. This post shows the full setup on a live OpenSearch 2.19.1 cluster managed by FoundryDB.
