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