Sometimes when you talk about things as a Linux user, people look at you oddly. For example when you tell them about installing software into a wine bottle in Linux. They'll probably just look at you in wonder and consider if you've gone mad.
Now the same sort of happens with Google sometimes. Even though Google is based on Linux, it will find quite a different kind of wine unless you e.g. add linux to the search. But even then it's not efficient and you might lose pages, as wine also works on Mac OS X and (yeah, I know) Windows itself.
But there's help: the Google Linux Search. It's not restricted to Linux as its name suggests, but excludes almost everything that doesn't have anything to do with computers (and which might distract the normal Google).
