• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu han - ((hanh tang) OR (anh tang)) cua dang cong doan ((phan dau) OR (hang dau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu han - ((hanh tang) or (anh tang)) cua dang cong doan ((phan dau) OR (hang dau))*".
