• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) tinh - hanh trung cua dung cong ban ((thong cap) OR (trung cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) tinh - hanh trung cua dung cong ban ((thong cap) OR (trung cap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) tinh - hanh trung cua dung cong ban ((thong cap) OR (trung cap))*.
