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.
