• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thi phuong) OR (thi truong)) ((x hoi) OR (x ho)). hieu van cac luc va thanh di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thi phuong) or (thi truong)) ((x hoi) OR (x ho)). hieu van cac luc va thanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ((thi phuong) or (thi truong)) ((x hoi) OR (x ho)). hieu van cac luc va thanh di cua triet*.
