• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty hang) OR (ty xang)) x hoi. lieu va cao duc ((va thanh) OR (va tinh)) ve cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty hang) or (ty xang)) x hoi. lieu va cao duc ((va thanh) OR (va tinh)) ve cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty hang) or (ty xang)) x hoi. lieu va cao duc ((va thanh) OR (va tinh)) ve cua triet*.
