• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((sang ma) or (sang tai)) hoi. ((hieu ve) OR (hieu va)) cham xuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang ma) OR (sang tai)) hoi. ((hieu ve) OR (hieu va)) cham xuc va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang ma) or (sang tai)) hoi. ((hieu ve) OR (hieu va)) cham xuc va hanh vi cua te*".
