I used to google for solutions for days and days until I found the solution. Looking back now, I think that was a bit too much googling. Now, I'm starting to just ask on stackoverflow and not google it at all. Is there an FAQ describing how much you should google, or is it based totally on my personal opinion and it's not a question?
In my eyes, the ideal approach when you have a question is:
If available, search the documentation (Thanks @Carlos)
Google. Try a few variations of your search.
Search on SO. Try a few variations of your search.
Once you have done that, and not found anything that you feel helps you, then ask on SO, but not earlier.
Asking something that could easily have been Googled is not a deadly sin, but try to avoid it. Otherwise, at some point, people start feeling like they're being used as mechanical turks for Googling, which is not the sites' point.
