• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - anh quang toan ban ((cong thanh) OR (cuon danh)) tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - anh quang toan ban ((cong thanh) or (cuon danh)) tuan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - anh quang toan ban ((cong thanh) or (cuon danh)) tuan cau*.
