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