• Performing a fuzzy search may retrieve terms with similar spellings: su cac tu nang x hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) ((vi cua) OR (di cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac tu nang x hoi. hieu ve cac xuc ((va hanh) OR (ban hanh)) ((vi cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac tu nang x hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) ((vi cua) OR (di cua)) triet".
• Adding a wildcard symbol may retrieve word variants: su cac tu nang x hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) ((vi cua) OR (di cua)) triet*.
