With advanced searching, you can do a complex, focused keyword search, combining up to four search terms and selecting a search field for each one. You can set search options to limit an advanced search, and you can search multiple databases. You do not need to know any special commands to do advanced searching.
You can combine search terms with the following connector words (also called logical operators, or Boolean operators):
: And - Search results must match the search text before And, and the search text after And.
Example:
A search for Subject: planets And Author: Asimov finds only
the works written by Asimov about planets. Any works about planets by
other writers and any works by Asimov about other subjects are ignored.
: Or - Search results can match the search text before Or, the search text after Or, or both search terms.
Example:
The search Any field: planets Or Author: Asimov finds all
works written by Asimov, as well as all works containing the word planets
in any search field.These last works include titles by Isaac Asimov
and titles by other authors.
: Not - Search results must match the search text before Not, but must not include the search text after Not.
Example:
A search that specifies Any field: planets Not Author: Asimov finds
works containing the word planets in any search field, except works
by Asimov.
