Refining your Google Search
So, i’ve just been reading the Official Google Blog, and I noticed they added this post.
There are some tips and tricks here to refine your Google search, or maybe try the simple “CheatSheet”.
Looking at it, i’ve used nearly all of the different operators except for “~”.
Appending the ~ before a search keyword means it will search for that word, and synonyms of that word.
I think I may try that one and see how I go!
Yah learn something new everyday 
I use the + and – to help refine my search everyday, I find it quite useful to searchfor a particular item that you know can also be confused with other things.
