• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ky ((mang may) or (nang ma)) hoa. hieu ve cac xuc ((va dinh) OR (va tinh)) ve cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky ((mang may) OR (nang ma)) hoa. hieu ve cac xuc ((va dinh) OR (va tinh)) ve cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky ((mang may) or (nang ma)) hoa. hieu ve cac xuc ((va dinh) OR (va tinh)) ve cua tu*".
