• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly nang ma hoi. hieu ve ((cac xuc) or (cam xuc)) ((van hanh) OR (ban hanh)) di cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang ma hoi. hieu ve ((cac xuc) OR (cam xuc)) ((van hanh) OR (ban hanh)) di cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang ma hoi. hieu ve ((cac xuc) or (cam xuc)) ((van hanh) OR (ban hanh)) di cua tu*".
