• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang xa hoi. hieu ve cam xuc ((van hanh) OR (ban hanh)) ((vi cua) or (de cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ve cam xuc ((van hanh) OR (ban hanh)) ((vi cua) OR (de cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ve cam xuc ((van hanh) OR (ban hanh)) ((vi cua) or (de cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ve cam xuc ((van hanh) OR (ban hanh)) ((vi cua) or (de cua)) tre*.
