What are Boolean Operators and how to I use them?

Boolean AND

AND


AND finds results containing BOTH of your search terms.

For instance a search for Alligators AND Crocodiles will find all the results that mention alligators and crocodiles but nothing that talks about just alligators or just crocodiles.

AND NARROWS your search.

For ex.

alligators - 43 results
crocodiles - 22 results
alligators AND crocodiles - 9 results

Google Google Tip Google automatically places an AND between your search terms. There is no need to include it when doing a Google search.
Boolean OR

OR

OR finds results that contain either of your search terms.

For instance a search for Alligators OR Crocodiles will find all the results that mention alligators or crocodiles or alligators and crocodiles.

OR BROADENS your search.

For ex.

Alligators - 43 results
Crocodiles - 22 results
Alligators OR crocodiles - 56 results

Google Google Tip: Google allows for OR searches. Simply type OR between your terms.
Boolean NOT

NOT

NOT eliminates a search term from your results.

For instance a search for Alligators NOT crocodiles will remove all the results that talk about crocodiles.

AND NARROWS your search.

For ex.

Alligators - 43 results
Crocodiles - 22 results
Alligators NOT crocodiles - 34 results

Google Google Tip: To exclude terms from your search in Google, use a minus sign (-) instead of the word NOT.
