• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - manh ((trung cap) OR (trung tuan)) thong cong tac ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - manh ((trung cap) or (trung tuan)) thong cong tac ((toan tap) OR (toan ban))*".
