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