• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien anh)) - hanh chinh ((cua trong) OR (cua truong)) duong manh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - hanh chinh ((cua trong) OR (cua truong)) duong manh toan ban".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien anh)) - hanh chinh ((cua trong) OR (cua truong)) duong manh toan ban*.
