I miss the good old days when Google search used AND rather than OR. Now it uses some kind of heuristic that frequently overwhelms my own instincts about how to narrow my search. I just tried an arbitrary search for the first thing that came to mind and everything was going great until I added a word whose occurrence evidently dwarfed my original search space: pistachio (18,400,000 results) pistachio cookies (2,570,000 results) pistachio cookies milk (1,220,000 results) pistachio cookies milk chocolate (1,210,000 results) pistachio cookies milk chocolate round (3,640,000 results) Maybe this was detecting the semantics of my search, for example “pistachio cookies” and “chocolate milk” as two separate concepts and OR’ing the set. But I don’t understand why it didn’t detect “round pistachio cookies”, but instead treated “round” as a completely different result set. This combined with the fact that quotes and plusses don’t always seem to make a keyword mandatory has really hindered usability for me. I sometimes find better results by typing keywords into domain-specific searches (sites like Stack Overflow). I wish there was a way to display Google’s interpretation of the keywords as something like SQL, the way that wolframalpha.com works, so that I could learn how to format my queries.
