Modifiers
You may modify your search by the inclusion of AND, OR and NOT operators. However, care must be taken with
the order they are entered. For example, AND operators take precedence over OR operators. To ensure that an OR operator is interpreted prior to
an AND operator, you can use parentheses to enclose the OR operator as follows:
"(a OR b) and C" will return documents containing A and C, or documents containing B and C. Alternatively, "a OR b and C" will return
documents containing a or documents containing b and c.
