• If you are trying to use Boolean operators, they must be ALL CAPS: su sach lo van ((tay co) OR (tay o)). hieu van chat xuc xa ((hang di) OR (hang vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach lo van ((tay co) or (tay o)). hieu van chat xuc xa ((hang di) OR (hang vi)) cua tre".
