Do you want to make your database searches fast and efficient?
Do you get frustrated when it seems there's nothing on your topic?
Get the results you need without having to sort through pages of hits, and save yourself time and frustration by using Boolean searches!
What is Boolean searching?
Boolean searching is a system for creating relationships between words by using Boolean operators. Databases respond best to Boolean searching.
What are Boolean operators?
They are short words (AND, NOT, OR) that when used to join keywords in searches, combine or exclude concepts from the search, leading to results that are more productive, focused, and targeted.
What does each Boolean operator do?
AND combines concepts (keywords) and requires that all them appear in the resulting sources. Note that AND narrows a search (you get fewer, more targeted results).
OR combines concepts and causes any of the terms (or all of them) to appear in the results. It's often used for synonyms or for related words. Note that OR broadens a search (you get more results). OR statements are placed in parentheses when combined with other Boolean operators.
NOT excludes terms, that is, it directs the database to ignore results that contain the word or words after OR.
How do you set up a Boolean search?
Connect your keywords with the operators that best conveys to the database what you want, and then search. If the results don't look right, try a new combination and search again.
