Watch the video below to help you refine your search in retrieving information.
Most databases allow for a symbol to be used at the end of a word to retrieve variant endings of that word. This is known as truncation.
Using truncation will broaden your search. For example,
bank* will retrieve: bank or banks or banking or banker or bankruptcy, etc.
Databases and Internet search engines use different symbols to truncate. In general, most of the Library's databases use the asterisk (*) ; however, the exclamation point (!) is used in LexisNexis. Check the database help screen to find the correct truncation symbol.
Be careful using truncation. Truncating after too few letters will retrieve terms that are not relevant. For example:
cat* will also retrieve cataclysm, catacomb, catalepsy, catalog, etc.
It's best to use the boolean operator "or" in these instances (cat or cats).
Using Boolean Operators
Keywords can be combined with other keywords using the AND (Boolean) operator to narrow your topic. For example:
supernatural AND pets
supernatural AND animals
supernatural AND human-animal communication
Keywords can be combined with synonyms using the OR (Boolean) Operator to broaden your search. For example:
supernatural OR afterlife stories
Quotation marks can be used to search phrases. For example:
Putting these terms in quotes means that the words will be searched as a phrase rather than each word separately.
