nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((thanh toan) OR (van toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((thanh toan) or (van toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((thanh toan) or (van toan)) tap*.
