At the beginning of the project, MixedBread's embedding model was small and leading the MTEB leaderboard [^1], hence I went with it.
Yes, I did binarize them for a faster search experience. However, I think the search quality degrades significantly after the first 10 results, which are same as fp32 search but with a shuffled order. I am planning to add a reranking strategy to boost better results upwards.
At the moment, this is plain search with no special prompts.
