• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty trang xa hoi. hieu ((vu cham) OR (vu kham)) tuc va ((danh vai) OR (doan van)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty trang xa hoi. hieu ((vu cham) OR (vu kham)) tuc va ((danh vai) or (doan van)) cau treo".
