Search techniques

To efficiently search library databases, use filters within the database and try search terms you think might be in the article's title, description, or full-text.

Techniques you can use to create database searches:


Use keywords in your searching. Select words or phrases which you predict will appear in an article title or description or full-text.


 Enclose a phrase (a string of 2 or more words) in quotation marks. Example: "global warming"


Truncate (cut off) search terms using an asterisk. The asterisk works as a wildcard. The search term:  recyc*  will retrieve articles which contain any word starting with r-e-c-y-c, like recycle, recycled, recycling, etc.


Combine multiple search concepts using the Boolean terms: AND, OR, NOT
