You have to always keep your 'head' and whenever possible verify all aspects and compare them to your situation. More often than not things that might seem relevant are completely irrelevant to your situation.
So true. My situation sometimes is that I'll get a SQL or Windows error that I can't solve on my own. I'll plug the error text or # into a search engine and get a bunch of hits. The advice given in these results can lead you down 3 or 4 different tangents leaving more confused than than when you started :-D. It's worth a little investigation just to see which avenue(s) might be relevant to your case.
And I agree with Keith that Google yields better results for these types of queries than Bing.
