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