• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang xa hoi. hieu ((van cam) OR (van lam)) luc ((van anh) OR (tuan anh)) vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang xa hoi. hieu ((van cam) OR (van lam)) luc ((van anh) or (tuan anh)) vi cuu tre".
