• If you are trying to use Boolean operators, they must be ALL CAPS: cho chinh sach - ((hanh trinh) OR (thanh cong)) cua dang cong san ((tan cua) OR (tang cua))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chinh sach - ((hanh trinh) or (thanh cong)) cua dang cong san ((tan cua) OR (tang cua))~".
• Adding a wildcard symbol may retrieve word variants: cho chinh sach - ((hanh trinh) or (thanh cong)) cua dang cong san ((tan cua) OR (tang cua))*.
