It got a lot worse recently when they added bad AI to it. Now it does dumb synonyms. Like I search for "doctorate" and it starts highlighting every instance of D alone, like the word "he'd". (Presumably trying to pick up Ph.D.?) For awhile searches for "A" would have it highlighting "the", too.
It's the least bad search--better than Yahoo, and Thunderbird desktop in my direct experience. However, I don't download the full message into Thunderbird out of fear of blasting through gmail bandwidth limits.
I’ve searched for a fairly rare word pair in the subject line of an email I want and gotten 20 irrelevant results. The only way to find it was by filtering senders and dates.
