Cloud Connector Service - Search Operation – Salesforce

I have a problem to get a result from the Salesforce connection.
The connections works fine. I also can insert contacts.
But if I want to get a contact from my Salesforce-account it doesn’t work. I can insert a searchstring, but the resultset contains not the expected fields that I determined while I was building the cloud connector service. The return value is a sObject type.
My Question: How could I work with sObjects in webmethods? Either I have to wrap this object in a suitable way or I need to get the required attributes as output of the cloud connector service.
Is there any solution for this problem?
Thank you in advance.
