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