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.

The smaller the index the faster it is searched.

for single word queries @@ should have the same performance as ilike with index disabled and better for complex queries.
