Advanced and Boolean Search Tips

There are times when searching for a particular term yields too many results and you need to refine and narrow your search. Refer to the table below for tips on how to refine your search.

Boolean Search Operators

Operator Effect Example

AND

Searches for documents that have both words in it. Searching for human AND body finds pages where both human and body occur somewhere in the page.
OR Searches for documents that have either word in it. Searching for human OR body finds pages where either human or body occurs somewhere in the page.
NOT Eliminates documents where the word is found. Searching for human NOT body finds pages where human occurs but body does not.

Special Search Characters

Operator Effect Example

(   )

The parentheses determine how ANDs and ORs are treated. Words within parentheses are considered a unit, and are considered first. Searching for anatomy OR (human AND body) finds pages where either anatomy or human and body occur somewhere on the page.
"   " Words or phrases within quotation marks are treated as a unit and searched for literally. This is especially helpful when the search term you are interested in contains the words "and" or "or." Searching for "rock and roll" finds pages where the string of words rock and roll occurs somewhere on the page.
* The asterisk functions as a wildcard symbol in searches. It designates any string of text that could stand in for the asterisk. Searching for cook* will find pages containing the words cooking, cooked, and cookies.
? The question mark stands in for any single character. It is more precise but often not as useful as the wildcard asterisk. Searching for ?ar?et will find pages containing target and carpet.
