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