• Performing a fuzzy search may retrieve terms with similar spellings: tu san cao tang van hoi. ((hieu ve) or (thien van)) ((ca dua) OR (ca da)) ban hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san cao tang van hoi. ((hieu ve) OR (thien van)) ((ca dua) OR (ca da)) ban hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san cao tang van hoi. ((hieu ve) or (thien van)) ((ca dua) OR (ca da)) ban hanh vi cuu tre*".
