The Advanced Search page walks you step by step through more complex searches that include combinations of keywords, Subject terms, author name or article title. It will also help you construct searches that exclude words from the results.
The picture below shows a search that combines video games in the Subject AND military as a keyword. Adding NOT flight in the Entire Document will include all articles that use the terms "video games" and military while excluding anything in that list of results that uses the term flight anywhere in the article. That means any article about the use of video games by the military for flight simulation would not be in the search results.
Go to the Boolean Searching Guide for more information on how to combine terms using AND, OR and NOT in searching.
The Wildcard symbol is a question mark: ?
It replaces one character. For example, the search for "wom?n" will find both "woman" and "women."
The Truncation symbol is an asterisk: *
It allows the user to search for alternate word endings. For example, the search for "comput*" will find "computer," "computers," "computing," "computation," and "computerized."
