Yes site name ... is company names or web site name ... so not many word in
each record ... but I don't understand why more words are more efficient
than few words ?? sorry ...
Well there are a couple of reasons but the easiest one is index size.
An ILIKE btree index is in general going to be much smaller than a gist

The smaller the index the faster it is searched.

index disabled and better for complex queries.
