public class RRFRanker
extends CreateCollectionReq.Function

The RRF reranking strategy, which merges results from multiple searches, favoring items that consistently appear. Read the doc for more info: https://milvus.io/docs/rrf-ranker.md Note: In v2.6, the Function and Rerank have been unified to support more rerank types: decay and model ranker https://milvus.io/docs/decay-ranker-overview.md https://milvus.io/docs/model-ranker-overview.md So we have to inherit the BaseRanker from Function, this change will lead to uncomfortable issues with RRFRanker/WeightedRanker in some users client code. We will mention it in release note. * In old client code, to declare a WeightedRanker: * RRFRanker ranker = new RRFRanker(20) * After this change, the client code should be changed accordingly: * RRFRanker ranker = RRFRanker.builder().k(20).build() You also can declare a rrf ranker by Function CreateCollectionReq.Function rr = CreateCollectionReq.Function.builder() .functionType(FunctionType.RERANK) .param("strategy", "rrf") .param("params", "{\"k\": 60}") .build();
