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