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