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