• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y nang ((x hoi) OR (x ho)). thi van phan duc ((tuan anh) OR (van phanh)) hai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang ((x hoi) OR (x ho)). thi van phan duc ((tuan anh) or (van phanh)) hai cua viet*".
