• Performing a fuzzy search may retrieve terms with similar spellings: vu dai kho tang van hoi. ((hieu ve) OR (hieu va)) cam xuc va dan de ((cua triet) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu dai kho tang van hoi. ((hieu ve) OR (hieu va)) cam xuc va dan de ((cua triet) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu dai kho tang van hoi. ((hieu ve) OR (hieu va)) cam xuc va dan de ((cua triet) or (cua tu))*".
