• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (mot chieu)) xanh - hanh tang cua thuong ((cong dan) OR (cong tan)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) xanh - hanh tang cua thuong ((cong dan) OR (cong tan)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) xanh - hanh tang cua thuong ((cong dan) OR (cong tan)) van ban*.
