Search Help

The text search engine allows queries to be formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and grouped with parentheses. The following are examples of valid searches:

information retrieval 
information or retrieval
information and retrieval
information not retrieval
(information not retrieval) and WAIS
web*    

In the above examples. the "or" operator is to specify search for pages with the first word or the second work. The same with the "and" operator, except both words must appear on the page found

The "Not" operator indicates to find pages with the first word and "NOT" the second word, so in the above example, only pages with the information found on them that do not have the word retrieval on them will be found.

Enclosing in parenthesis causes a search of items in the parenthesis to be completed first.

Asterisks indicate a wildcard search
