• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu tinh) OR (lieu tinh)) - hanh truong ((cua truong) OR (cua nhung)) cong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu tinh) OR (lieu tinh)) - hanh truong ((cua truong) or (cua nhung)) cong dan toan ban".
