Keywords may be separated by AND and/or OR statements for greater control of the search results.
For example, Rose AND dozen would generate a result set that contain both words. However, for rose OR lilies, the result set returned would contain both or either words.
Exact matches can be searched for by enclosing keywords in double-quotes.
For example, "dozen roses" would generate a result set which match the exact string.
Brackets can be used for further control on the result set.
For example, Sympathy and (wreath or bouquet or "casket spray").
