• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - hanh doanh cua ((ban cong) OR (van cong)) tap toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) xanh - hanh doanh cua ((ban cong) OR (van cong)) tap toan ban*.
