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