• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang tay hoi. hieu ve cac du tan anh ((((hai cua) OR (lai cua))) OR (dai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang tay hoi. hieu ve cac du tan anh ((((hai cua) OR (lai cua))) or (dai cua)) triet".
