Perhaps you should try some spelling variations:
"diskursmuster / discharge patterns" » "diskursmuster / disease patterns"
"diskursmuster / change patterns" » "diskursmuster / changing patterns", "diskursmuster / usage patterns", "diskursmuster / chart patterns"

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: "((\"diskursmuster / discharge patterns\") OR (\"diskursmuster / change patterns\"))".
• Removing quotes may allow a broader search: (( diskursmuster / discharge patterns ) OR ( diskursmuster / change patterns )).
• Adding a wildcard symbol may retrieve word variants: (("diskursmuster / discharge patterns") OR ("diskursmuster / change patterns"))*.
