• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y tang) OR (6 tang)) van hoi. ((hieu ve) OR (lieu va)) nhan luc va danh dau cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y tang) OR (6 tang)) van hoi. ((hieu ve) or (lieu va)) nhan luc va danh dau cua triet".
