Perhaps you should try some spelling variations:
"sorgeverhaltnisse" » "korperverhaltnisse", "lageverhaltnisse", "energieverhaltnisse"
"warmeverhaltnisse" » "krafteverhaltnisse"
"kraftverhaltnisse" » "krafteverhaltnisse", "krafteverhaltnissen", "krafteverhaltnis"
"wasserverhaltnisse" » "wissensverhaltnisse", "klassenverhaltnisse", "grossenverhaltnisse"
"massverhaltnisse" » "passungsverhaltnisse"

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: (("sorgeverhaltnisse" OR "warmeverhaltnisse") OR ("kraftverhaltnisse" OR ("wasserverhaltnisse" OR "massverhaltnisse"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sorgeverhaltnisse\" or \"warmeverhaltnisse\") or (\"kraftverhaltnisse\" or (\"wasserverhaltnisse\" OR \"massverhaltnisse\")))".
• Removing quotes may allow a broader search: (( sorgeverhaltnisse or warmeverhaltnisse ) or ( kraftverhaltnisse or ( wasserverhaltnisse OR massverhaltnisse ))).
• Adding a wildcard symbol may retrieve word variants: (("sorgeverhaltnisse" or "warmeverhaltnisse") or ("kraftverhaltnisse" or ("wasserverhaltnisse" OR "massverhaltnisse")))*.
