Re: Querying a table with jaccard similarity with 1.6 million records take 12 seconds

This is showing many false positives from the index scan that get removed when the actual values are examined. With such a long search parameter, that does not seem surprising. I would expect a search on "raj nagar ghaziabad 201017" or something like that to yield far fewer results from the index scan. I don't know GIN indexes super well, but I would guess that including words that are very common will yield false positives that get filtered out later.
