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