I'm a little confused by your statement that "Meilisearch decided to use hybrid search and avoid fusion ranking" when your website [1] says "Hybrid search re-ranking: The final step involves re-ranking results from both retrieval methods using the Reciprocal Rank Fusion (RRF) algorithm."
Can you clarify what you mean by "fusion ranking"?
All hybrid search requires a method to blend keyword and vector search results. RRF is one approach, and cross-encoder-based rerankers is another.
