• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh tang) OR (anh tang)) cua dang cong ((dan toan) OR (thanh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh tang) OR (anh tang)) cua dang cong ((dan toan) or (thanh toan)) cau*".
