Perhaps you should try some spelling variations:
"wird gust responses" » "wird gust response", "wird host responses", "wird best responses", "wird gut responses", "wird aus responses", "wird bunt responses"
"wird test responses" » "wird host responses", "wird best response", "wird stress responses", "third test responses", "wird teil responses"

Try widening your search to All Fields.

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wird gust responses\") OR (\"wird test responses\"))".
• Removing quotes may allow a broader search: (( wird gust responses ) OR ( wird test responses )).
• Adding a wildcard symbol may retrieve word variants: (("wird gust responses") OR ("wird test responses"))*.
