Perhaps you should try some spelling variations:
mixed initiativen » mixed initiative, die initiativen, failed initiatives
initiativen als » initiativen des, initiativen und, initiativen fur
mixed initial » mixed martial, mixed initiative
initial part » initial post, initial phase, initial plan

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 part ) OR ( mixed initiativen als ))*.
