Keywords may be separated by AND and/or OR statements for greater control of the search results.For example, Aqua AND Tech would generate results containing both words. However, for Whisper OR Penguin, the results would contain both or either words.Exact matches can be searched for by enclosing keywords in double-quotes.For example, "Whisper 20" would generate results which match the exact string.Brackets can be used for further control on the result set.For example, Aqua and ("Hex 5" or "5").
