• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((trang xa) OR (trang va)) hoi. ((hieu ve) OR (hieu van)) cam duc tan thanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((trang xa) OR (trang va)) hoi. ((hieu ve) or (hieu van)) cam duc tan thanh hai cua te".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((trang xa) OR (trang va)) hoi. ((hieu ve) or (hieu van)) cam duc tan thanh hai cua te*.
