Search strategies

When searching for information, there are a number of techniques to use that will help refine your search results .  You can use these strategies when looking for information from the library databases or from a search engine such as Google.

Advanced Search Strategies

Boolean Operators

One of the easiest ways to refine your search is to use the Boolean operators. The three most common Boolean operators are AND, OR, and NOT, but there are others available. The operators AND and NOT will narrow your search and OR will usually increase your search results. (The AND operator is not necessary in Google; Google automatically adds the AND between words unless a phrase is put in quotation marks.)

The images below explain differences between the Boolean operators.
