• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach ty) OR (sach y)) hang van hoi. hieu van nam loc va hanh ((de cua) OR (te cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ty) OR (sach y)) hang van hoi. hieu van nam loc va hanh ((de cua) or (te cua)) triet".
