• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) sang tao hoi. hieu van cam xuc ((ban anh) OR (ban danh)) vi va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach y)) sang tao hoi. hieu van cam xuc ((ban anh) OR (ban danh)) vi va triet*".
