Hi Oleg,

you didn't show us explain analyze of your select.

I didn't because I didn't expect any reaction to it - my understanding is that trigram matching for phrases is not recommended because of the performance. Do you believe that I SHOULD expect good performance from trigram matching on phrases (a sopposed to words)?
