• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y lang ha hoi. ((thien van) OR (thi van)) lam luc ((va hanh) OR (va thanh)) trinh cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y lang ha hoi. ((thien van) or (thi van)) lam luc ((va hanh) OR (va thanh)) trinh cua cu".
