• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky tang ((lai hoi) or (cac khoi)). hieu ((ve cam) OR (ve cham)) xuc va danh sai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky tang ((lai hoi) OR (cac khoi)). hieu ((ve cam) OR (ve cham)) xuc va danh sai cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky tang ((lai hoi) or (cac khoi)). hieu ((ve cam) OR (ve cham)) xuc va danh sai cau tren*".
