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