• If you are trying to use Boolean operators, they must be ALL CAPS: ho lieu tinh - hanh luong quang nhung cong van ((((toan cau) OR (toan tap))) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - hanh luong quang nhung cong van ((((toan cau) OR (toan tap))) or (toan ban))*".
