Boolean logic defines logical relationships between terms in a search. The Boolean search operators are and, or and not. You can use these operators to create a very broad or very narrow search. Use these terms in the library's Discovery search or in the library catalogue using the advanced search option.

The wildcard is represented by a question mark ? or a pound sign #.
To use the ? wildcard, enter your search terms and replace each unknown character with a ?. This search finds all citations of that word with the ? replaced by a letter.
For example, type ne?t to find all citations containing neat, nest or next. This search does not find net because the wildcard replaces a single character.
Note: When searching for a title that ends in a question mark, the symbol should be removed from the search in order to ensure results will be returned.
To use the # wildcard, enter your search terms, adding the # in places where an alternate spelling may contain an extra character. This search finds all citations of the word that appear with or without the extra character.
For example, type colo#r to find all citations containing color or colour.
Note: Searching the U.S. spelling of words will also include some spelling variations (i.e. colour or odour) but not all spelling variations.
When using the pound/hash (#) wildcard, plurals and possessives of that term are not searched. For example, when running a search for the term colo#r, the terms "colors" and "colours" will not be searched (which they are by default when using the singular "color" or "colour" without a wildcard operator).
Truncation is represented by an asterisk (*). To use truncation, enter the root of a search term and replace the ending with an *.
For example, type comput* to find the words computer or computing.
Note: The Truncation symbol (*) may also be used between words to match any word.
For example, a midsummer * dream will return results that contain the exact phrase, a midsummer night’s dream.
Note: Wildcards and Truncation can not be combined for a term in a search. For example, a search for p#ediatric* would be the same as a search for P*

Keyword searches are similar to Internet searches with Google in that the database will look for the words you use wherever they may be on a page. Regardless of whether the word is in a title, author name, place of publication or footnote, the page will be returned as a result.
