Search Tips

If you would like to search for multiple terms at the same time, please surround each term with quotations (i.e. "brain" and "function," or "Psychology" or "experiment"). If you want to refine your search, use the special search operators listed below in your search criteria. Note: Searches are not case-sensitive.

AND Searches for documents that have both words in it.
OR Searches for documents that has either word in it.
NOT Eliminates documents where the word is found.
(Parentheses) Determines how ANDs and ORs are treated. Words within parentheses are considered as a unit, and are considered first.
"Quotation marks" Quoted words or phrases are searched for literally.
* A wildcard that stands for any number of characters. Ex.: a search for Glo* would find Global, Globalization, Globe, etc.
