To help refine your keyword searches it is recommended that you use Boolean operators (AND, OR, and NOT). These operators help connect your search terms and are used to broaden or narrow your search results.
AND - Placing AND between search terms instructs the database that both terms must appear somewhere in the results list.
NOT - When you place NOT before a keyword search it instructs the database that the keyword must not appear anywhere in the entry.
OR - Using OR between keywords instructs the database to search either or both of the keywords in the results list.
You are able to combine any of the Boolean operators to build very specific searches.
