• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y lang) OR (tay lang)) xa hoi. ((hieu va) OR (hieu qua)) cac cac ban thanh lap cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y lang) or (tay lang)) xa hoi. ((hieu va) OR (hieu qua)) cac cac ban thanh lap cua triet*".
