You can also use OR to
combine keywords in a search.
Using OR means that an article
will be retrieved if it contains
either keyword. OR is best used
to search for synonyms of
a concept. Because any one of
these words could show up in
your articles, OR broadens
your search.
Internet OR
Web
Using this search in a
periodical index would find
all of the citations that
mention either
Internet
or Web.
Internet OR
Web
OR
online OR
digital
OR
wired
You can use OR many
times in a single search.
You can make very complex
searches by combining the use of
AND and OR in a technique called
nesting. Did you know that
the terms AND and OR are called
Boolean operators? |
