• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) thu ((hang x) OR (chang xu)) hoi. hieu van cac luc gia thanh di su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) thu ((hang x) OR (chang xu)) hoi. hieu van cac luc gia thanh di su triet*".
