• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((((lo hang) OR (le hang))) OR (le thang)) xa hoi. hieu va ngay duc va thanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((((lo hang) OR (le hang))) or (le thang)) xa hoi. hieu va ngay duc va thanh vai cua triet".
