Similarity search can be made orders of magnitude faster if we’re willing to trade some accuracy; that is, deviate a bit from the reference result. For example, it may not matter much if the first and second results of an image similarity search are swapped, since they’re probably both ...

For similarity_search_with_score, if thesimilarity_search_with_scoredocumentation is correct saying that "List of documents most similar to the query text with L2 distance in float. Lower score represents more similarity.", then the result fromsimilarity_search_with_scoreshould have matched the ide...
