Boolean : In Boolean searching, an "and" between two
words or other values (for example, "pear AND apple")
means one is searching for documents containing both of the words
or values, not just one of them. An "or" between two
words or other values (for example, "pear OR apple")
means one is searching for documents containing either of the
words. A "not" between two words or other values (for
example, "cat NOT lion") means one is searching for
documents containing cats that aren't really big cats. Parentheses
can also be used when conducting an advanced search. For example:
"art AND (school OR college)" - would be used for a
search for records containing information about art schools or
colleges. For those not familiar with boolean searching we suggest
