NOT
Eliminates articles containing the second term even when the first term is present; this will
narrow
the search.

QUOTATION MARKS
Use quotation marks " " before and after a phrase, two or more words that must be together in a defined order.
This lets the database know that you want to search for this phrase, and not the individual words that make up the phrase.
Using Nesting with Operators
Use nesting to build a more complex search by putting keywords and/or phrases in parentheses to determine their relationship when more than one operator is used.
AND
Retrieves only articles that contain all the terms and will
narrow
the search.
OR
Retrieves articles with
any
of the terms and will
broaden
the search.
