Researchers often look for comprehensive information about a topic -- rather than
just taking five articles that look pretty good. They use a technique called nesting
which lets them do many searches at once.
For example:
(community or communities) and (Internet or Web or online)
This one keyword search in a periodical index would find articles that had one of the
following combinations:
community and Internet
community and Web
community and online
communities and Internet
communities and Web
communities and online
Constructing these searches may take a little longer, but it will save you from creating
many searches and remembering what combinations you have already tried.
