• If you are trying to use Boolean operators, they must be ALL CAPS: su sach va trang xa hoi. hieu ve ((cham tuc) OR (pham thuc)) va ((dang van) OR (doanh van)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach va trang xa hoi. hieu ve ((cham tuc) OR (pham thuc)) va ((dang van) or (doanh van)) cuu tre".
