2c fortschritte » 2 fortschritte, 23 fortschritte, 24 fortschritte
c fortschritte » 5 fortschritte, 2 fortschritte, 3 fortschritte

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22recent results in cancer research%((2c fortschritte) OR (c fortschritte)) der krebsforschung heute%c3%((a8s dans) OR (ans dans)) les recherches sur les cancer%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22recent results in cancer research%((2c fortschritte) or (c fortschritte)) der krebsforschung heute%c3%((a8s dans) OR (ans dans)) les recherches sur les cancer%22".
• Adding a wildcard symbol may retrieve word variants: %22recent results in cancer research%((2c fortschritte) or (c fortschritte)) der krebsforschung heute%c3%((a8s dans) OR (ans dans)) les recherches sur les cancer%22*.
