• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang tai hoi. lieu ((va cam) OR (va cac)) xuc va danh kien ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang tai hoi. lieu ((va cam) or (va cac)) xuc va danh kien ((cua triet) OR (va triet))".
