case class ReciprocalRankFusion(windowSize: Option[Int] = None, rankConstant: Option[Int] = None) extends SearchScoring with Product with Serializable
Combine vector and non-vector query results using reciprocal rank fusion. This merges the result by rank, and is the recommended approach.
Only applicable when the vector.SearchRequest includes both a queries.SearchQuery and a vector.VectorSearch.
- windowSize
how many results per list are used for score fusion.
- rankConstant
sets the rank constant used in the RFF algorithm.
