>I do this: When Google fails me, I try the other search engines. So far, they fail me too. There's a case you're missing - that Google doesn't outright fail, but its performance is inferior to Yahoo's or Microsoft's. For example, Google may have the page you're looking for at the bottom of the first page of results (in which case you'd probably be satisfied and not try another search engine), but Yahoo or Microsoft might list it as the first result, which would be superior performance.
