• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((song xa) OR (song cua)) hoi. hieu va chat xuc ((van anh) OR (van thanh)) lai va trien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((song xa) or (song cua)) hoi. hieu va chat xuc ((van anh) OR (van thanh)) lai va trien".
