Connecting Web Services 
Enterprise Search supports third-party Web search services. To allow search results from a Web service to be displayed in the Search UI, you connect the Web service from which you want to include results to Enterprise Search.
The Web service must be based on SOAP.
The Web service must have a simple structure: No complex input or output signature.
WSDL must not require authentication.
To connect a Web service to Enterprise Search you require the following information:
URL of the WSDL file
If an API key is required, you must get one from the Web service provider.
Recommendation
