• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang ma) OR (nang cao)) hoi. ((hieu vu) OR (hieu va)) cham sac van kinh tay cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang ma) OR (nang cao)) hoi. ((hieu vu) or (hieu va)) cham sac van kinh tay cau tren~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((nang ma) OR (nang cao)) hoi. ((hieu vu) or (hieu va)) cham sac van kinh tay cau tren*.
