Connecting To Data Provider Services 
You can include external search service providers in SAP NetWeaver Enterprise Search and use the accompanying data provider services (DPS) to search data in customer-specific systems and third-party systems that are not ABAP-based.
SAP NetWeaver Enterprise Search extracts the data from a system that has implemented the DPS services.
For more information about the interface to the data provider services and the programming model, see the Developer's Guide.
The DPS provider has exposed the search template service and the search data service and made available the URLs to the logical ports (“SOAP Web Service Endpoints”).
Import the models.
Create a logical port for the search template service.
Note
You can reuse existing logical ports if the port makes available more than one software component, namespace, or model.
Import the available models including the software component.
For more information, see Importing Models for the Data Provider Service.
You generate a DPS search object connector based on the model.
For more information, see Creating DPS Search Object Connectors.
