Google Searches

I've started subscribing to the Gooru newsletter,  which gives "tips, tricks, and tools" for all things google, and came across this helpful post on 12 Google Search Tricks you probably didn't know.  I particularly liked the tip that you can use quotes and a subtraction sign to remove any words you don't want included in the search - for example "Titanic-movie."   I also recently set up a Google custom search for my space colony research project because I didn't want the students getting bogged down in highly technical websites.  I was amazed at how easy it was to set up!  If you'd like to know how, I'd be happy to show you, or you can check out this description.   Do you have any good Google search tricks?
