Using quotation marks for a phrase tells Google to search for that exact phrase - instead of looking for each word individually. For example:
Google uses AND by default in all your searches - you don't actually have to type in the word "AND."
For example, if I typed cat dog into Google, it would search for cat AND dog.
Google uses OR like other search services.
If we search for "cat OR dog" in Google, we should get all the results for cat, and all the results for dog.
Google uses a dash or minus sign (-) instead of the word NOT.
For example, if you wanted to search for cats but not dogs, you would type cats -dogs into Google. You can also exclude phrases (ex. cats -"cute dogs") or multiple words (ex. cats -musical -dogs).
Truncation lets you search for related words that have the same root. Guess what? Google does this for you automatically. You've probably noticed this already. Here's an example - if I search for west in Google, I also get a result for Western.
