How to get the most from Google searches

I've been planning to write a post about how to make the most of Google searches, but discovered Robert Ragan has already made a video tutorial which demonstrates some really useful techniques - you can see that above.

I hadn't thought of using the misspelling 'geneology' in my searches - I'm a word nerd, I like to make sure I use correct spellings - but it is a good idea, because not everyone will spell the word correctly, and it would be a shame to miss useful information simply for the sake of one letter. On the other hand, I'd make an addition to combined searches in the shape of the term "family history" which has turned up some interesting results when combined with a surname.
