• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach loai san ma hoi. ((lieu van) OR (lieu va)) nam thuoc va hanh di ((cua viet) OR (cua vat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach loai san ma hoi. ((lieu van) or (lieu va)) nam thuoc va hanh di ((cua viet) OR (cua vat))*".
