Search Help red links provide explanations of the
terms and concepts.
This product supports
Boolean logic (and, or, not). For example, if you type in Washington
and history, your results list will include those that include "Washington"
and "history" in the same entry, but not the word "and."
It also supports the use of quotations to join terms.
For example if you type "Yakima Washington" your results will
be different than if you type Yakima Washington.
