• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty hang) OR (thi hang)) ha hoi. lieu va ((nay truc) OR (cau truc)) xa hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty hang) OR (thi hang)) ha hoi. lieu va ((nay truc) or (cau truc)) xa hanh vi cua triet".
