Perhaps you should try some spelling variations:
"mixed initiativen als" » "mixed initiative als", "die initiativen als", "failed initiatives als", "mixed initiativen des", "mixed initiativen und", "mixed initiativen fur"
"mixed initial art" » "mixed martial art", "mixed initiative art", "mixed initial part", "mixed initial app", "mixed initial agent"
"mixed initial care" » "mixed martial care", "mixed initiative care", "mixed initial case", "mixed initial career", "mixed initial charge"

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: (((("mixed initial art") OR ("mixed initial care"))) OR ("mixed initiativen als")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mixed initial art\") OR (\"mixed initial care\"))) or (\"mixed initiativen als\"))".
• Removing quotes may allow a broader search: (((( mixed initial art ) OR ( mixed initial care ))) or ( mixed initiativen als )).
• Adding a wildcard symbol may retrieve word variants: (((("mixed initial art") OR ("mixed initial care"))) or ("mixed initiativen als"))*.
