• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y ((sang ma) OR (sang tao)) hoi. hieu ve cau luc va dinh ((du cua) OR (duy cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y ((sang ma) or (sang tao)) hoi. hieu ve cau luc va dinh ((du cua) OR (duy cua)) triet*".
