mang cua » manh cua, dung cua, ban cua
ban quan » van quan
van toan » van tuan, van thanh, manh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sang - hanh ((mang cua) OR (ban quan)) dang cong ((van toan) OR (van tan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sang - hanh ((mang cua) or (ban quan)) dang cong ((van toan) OR (van tan)) tap*".
