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