• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky sang lai hoi. ((hieu su) or (tieu su)) chao xu ban thanh vi ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang lai hoi. ((hieu su) OR (tieu su)) chao xu ban thanh vi ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang lai hoi. ((hieu su) or (tieu su)) chao xu ban thanh vi ((cua te) OR (cua tu))".
