• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (theo chieu)) xanh - hanh hang cua nhung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (theo chieu)) xanh - hanh hang cua nhung ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (theo chieu)) xanh - hanh hang cua nhung ((cong dan) OR (cong san)) toan cau*.
