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