The three most commonly used Boolean operators are: AND, OR, and NOT.
In Boolean searching, an "AND" operator between two words (for example,
"apples AND oranges") tells the search engine to find documents that contain
both of these words. An "OR" operator (for example, "pear OR apple") tells
the search engine to find documents that contain either of the words. A "NOT"
operator (for example, "berries" NOT raspberries") tells the search engine to
find documents containing only one of the words. |
