Search Tips

When searching online, various words are used to help broaden or narrow your search.  Here are a few tips you should know before searching any academic database:

Boolean operators: Most internet and electronic databases follow the rules of boolean logic.  Boolean logic refers to the relationships (connections or differences) between different search terms.  The most common boolean operators are:

AND - used to narrow a search and establish more relevant results by linking keywords together (e.g. "behavioural" and "psychology").

OR - broadens a search and get more results. Typically used for synonyms and words with variant spellings (e.g. "self-actualization" and "self-identity").

NOT - use to narrow a search and get more relevant results (e.g. "behaviouralism" not "humanism").

Truncation: used to find similar words with different endings

e.g. human* searches "human and humans"

e.g. educat* searches "education", "educate", "educational" etc 

asterisk (*)  searches for various different endings of a word in most databases (including York University), however LexisNexis uses an exlamation mark (!).
