• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR (chuc nang)) - thanh trung thanh duong cong ((tac tran) OR (tan tran)) tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or (chuc nang)) - thanh trung thanh duong cong ((tac tran) OR (tan tran)) tap".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (chuc nang)) - thanh trung thanh duong cong ((tac tran) OR (tan tran)) tap*.
