• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) xanh - thanh tung cua dung trong vang ((tao cau) OR (tan ca))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) xanh - thanh tung cua dung trong vang ((tao cau) or (tan ca))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) xanh - thanh tung cua dung trong vang ((tao cau) or (tan ca))*.
