Our Advanced Search function supports Boolean searching across the entire
catalogue. The power of Boolean searching is based on combinations of
keywords with connecting terms called operators. We use the operators AND
and OR to assist you to perform accurate searches without producing many
irrelevant publications.
 |
In a Boolean search for water AND environment, AND means "I
want only publications that contain both words."
|
 |
In a Boolean search for english OR language, OR means "I want
publications that contain either word. I don't care which word."
|
 |
AND and OR must be typed in upper case.
