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