How to do Boolean keyword searches
Searches are NOT CASE SENSITIVE. Enter one or more search terms as follows:
- All search terms must consist of at least three characters (not counting
any attached operators).
- To indicate that all items retrieved MUST CONTAIN A TERM, precede
it with an addition operator ( + ).
- To indicate that all items retrieved MUST NOT CONTAIN A TERM,
precede it with a subtraction operator ( - ).
- To indicate that A TERM IS OPTIONAL (Boolean "or"),
do not precede it with any operator.
Example: microfilm microfilming
- A single word without an operator is treated as a required word;
thus a search for "microfilm" is the same as a search for "+microfilm".
- A TERM MAY BE TRUNCATED by appending an asterisk ( * )
to the end of the truncated term.
- As an exception to the first rule, a term ending with an asterisk must consist of at least one character (not counting the
asterisk or any attached operators).
- To SEARCH FOR A PHRASE, put the phrase in double-quotes. (You
can use "+" and "-"
with a phrase, but not "*".)
+"archival documents" +canad*
Note: Hyphenated terms are treated as two separate terms. To search for a hyphenated term, treat it as a phrase.
If search terms are entered in more than one Boolean search field, the search will
be performed as an "AND" search on the multiple fields.
