• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach tien ((tu bach) OR (tu cach)) ha he thong ) OR ( tu sach thu vu anh khoa thu thang ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach tien ((tu bach) OR (tu cach)) ha he thong ) or ( tu sach thu vu anh khoa thu thang ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach tien ((tu bach) OR (tu cach)) ha he thong ) or ( tu sach thu vu anh khoa thu thang ))*.
