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