Alpha Parameter

Alpha Parameter

This is an optional parameter in hybrid search queries that determines the weighting of each search algorithm during the re-ranking process. An alpha value of 0 gives full weight to the sparse vector (BM25), 1 gives full weight to the dense vector, and 0.5 gives equal weight to both.
