How about setting alpha=0.0? ```python query_engine = index.as_query_engine( vector_store_query_mode="hybrid", similarity_top_k=2, alpha=0.0 ) ```

> @maxjakob 您好，请问这个必须要求ES的高级版才可以使用是吗，我更新了llama-index-vector-stores-elasticsearch，在混合搜索的时候 ，一直出错“elasticsearch.AuthorizationException: AuthorizationException(403, 'security_exception', 'current license is non-compliant for [Reciprocal Rank Fusion (RRF)]')” You can also use a 30-day trial version of ES with `xpack.license.self_generated.type=trial`. See https://docs.llamaindex.ai/en/stable/examples/vector_stores/ElasticsearchIndexDemo/

How about `CitationQueryEngine`? https://docs.llamaindex.ai/en/stable/examples/query_engine/citation_query_engine/
