Keywords may be separated by AND and/or OR statements for greater control of the search results.
For example, Wooden AND John would generate a result set that contain both words. However, for wooden OR John, the result set returned would contain both or either words.
Exact matches can be searched for by enclosing keywords in double-quotes.
For example, "silver icon" would generate a result set which match the exact string.
Brackets can be used for further control on the result set.
For example, John and (silver or wooden or "gold plated").
