• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) y ((nang ma) OR (tang ma)) hoi. lieu va cam luc va danh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) y ((nang ma) or (tang ma)) hoi. lieu va cam luc va danh di cua te*".
