It does not truncate
words. For example, if you type encyclopedia, your
results list will not include encyclopedias.
It does not support
boolean logic (and, or, not). For example, if you type in Washington
and history, your results list will include those that include all
three words in the same entry, but also those that include any of the three
terms including the word "and."
It does support 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.
