• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho kieu) OR (so kieu)) tinh - thanh tung cua khong ((duong thanh) OR (dong thanh)) thang cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho kieu) or (so kieu)) tinh - thanh tung cua khong ((duong thanh) OR (dong thanh)) thang cap".
• Adding a wildcard symbol may retrieve word variants: ((ho kieu) or (so kieu)) tinh - thanh tung cua khong ((duong thanh) OR (dong thanh)) thang cap*.
