Boolean
NOT
The
Boolean NOT asks that
documents with a certain term in them be excluded. Some search
engines support a minus sign rather than the term not. The minus
sign between terms serves the following functions:
NOT
puts search terms in context and excludes unwanted documents.
(marihuana OR marijuana OR grass) NOT
lawn
track* AND middle school NOT track and field
This search will retrieve documents about tracks or
tracking in middle school, not track and field programs
in middle school.
Note: Use the minus sign to exclude words in Google.
Truncation
Truncation
(also called stemming) allows users to retrieve any document
with the search term in one form or another. Simply add
an asterisk to the stem of a word as follows:
research*
will bring up documents with any of the following forms of
the word:
researches
researcher
researched
researching
You
can use truncation to bring up documents with the singular and
plural forms of the word
child*
will bring up child or children
Note: Child*
might also produce "false hits," documents that are
irrelevant, such as those with childless, childish, or childlike
in them.
Note:
Google does not support truncation.
