Reference documentation and code samples for the Vertex AI v1beta1 API class RagEmbeddingModelConfig.Types.SparseEmbeddingConfig.Types.Bm25.
Optional. The parameter to control document length normalization. It
determines how much the document length affects the final score. b is
in the range of [0, 1]. The default value is 0.75.
Optional. The parameter to control term frequency saturation. It
determines the scaling between the matching term frequency and final
score. k1 is in the range of [1.2, 3]. The default value is 1.2.
