What is Boolean searching?

Boolean searches use three operational terms: AND, OR and NOT

Boolean

Boolean searches using AND, OR and NOT

AND Search:

I want to look for images that have both dogs and cats in them.

My search would be inputted into the search bar as: dogs AND cats.

I would get only pictures that had both dogs and cats in them.

AND can help you narrow down a search where you have too many results. I only want pictures of collies AND tabbies.

OR Search:

I want to look for images that have dogs or cats.

My search would be inputted into the search bar as: dogs OR cats.

I would get pictures of dogs and cats together as well as images of just dogs or just cats.

OR can help you widen your search if you don’t get enough results, particularly if you don’t know the correct terminology: dogs OR puppies OR cats OR kittens.

NOT Search:

I want only images of dogs, no images of dogs and cats together or cats.

My search would be inputted into the search bar as: dogs NOT cats.

I would get pictures that only had dogs in them.

NOT can help when you get too many results that are not relevant to what you want. I want dogs NOT puppies.
