It is a simple question but I have realized that maybe my usage of search engines (mainly Google) is rather naive.
I am aware of using quotes ("") to search for exact occurrence of multiple words, and the asterix (*) as a placeholder for any word. I am also aware of "filetype:" and "Define:"
Could somebody here please recommend any nice online tutorials/books/videos (preferably videos) for mastering Google search? Or perhaps if you could list some nice tips & tricks you've learnt along the way - even if it just involves suggestions for best practice.
