• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi trieu) OR (doc hieu)) tinh - hanh trinh cua dung ((cong tan) OR (cong san)) nhanh cay~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi trieu) or (doc hieu)) tinh - hanh trinh cua dung ((cong tan) OR (cong san)) nhanh cay~".
• Adding a wildcard symbol may retrieve word variants: ((doi trieu) or (doc hieu)) tinh - hanh trinh cua dung ((cong tan) OR (cong san)) nhanh cay*.
