Creating BO Search Object Connectors 
To connect an SAP R/3 system to SAP NetWeaver Enterprise Search, you must create search object connectors for all business object types that you want to include in your search. You can do this quickly and easily by using the search object connector models delivered with SAP NetWeaver Enterprise Search.
Note
If you have other requirements that are not covered by the models in SAP NetWeaver Enterprise Search, you can also create your own search object connector models or change existing search object connector models.
