Integration of Sharepoint to SOLMAN containing TREX search engine

Hi All,

We are creating a new portal in SharePoint 2013 .

We want to integrate SAP search results with SharePoint 2013 search results.

We are using TREX search Engine for SAP Search, can we integrate TREX search result in SharePoint.

Can we use TRex API (using WebServices)to get TRex results, if yes please let me know how to fetch the Search Results OR is it possible to integrate using NW Gateway Service in order to fetch the results keeping TREX in mind?

Requesting you to give a word of advise regarding this integration.

Thanks in advance,

Regards,

Chaitanya
