Don't go there, Alta Vista is owned by Yahoo, and they've destroyed it. Even before they messed it up, Alta Vista's results seemed to be derived from Google's.

I really need an alternative to Google. I search for industrial stuff a lot and I'm getting pages of "pollution" results (globalspec, thomas, alibaba, etc...) Google really needs a "never show me results from these sites" option.

Hmmm... interesting... I just tried searching for "ac motor" and "anemometer" and got good results for both, the "pollution" sites were not even on the first two pages of results...
