• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((((ty hang) OR (thu hang))) OR (ly hang)) xa hoi. hieu van cac tuc ha thanh moi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((((ty hang) OR (thu hang))) or (ly hang)) xa hoi. hieu van cac tuc ha thanh moi cua triet*".
