Searching multiple Content Server Portlets

Question

I am able to search single Content Server Portlet and get results using following lines of code.
IPTSession ptSession = new InProcSession();
ptSession.Connect(AppSettings.PTUserName(), AppSettings.PTPassword(), null);
IPTSearchRequest ptSearchRequest = ptSession.GetSearchRequest();
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_APPS, PT_SEARCH_APPS.PT_SEARCH_APPS_CONTENT);
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_ASSOC_PORTLET_ID, 10468);
IPTSearchQuery ptSearchQuery = ptSearchRequest.CreateBasicQuery(query, null);
IPTSearchResponse ptSearchResponse = ptSearchRequest.Search(ptSearchQuery);
return ptSearchResponse;
However Type Cast exception comes at run time when we pass array containing multiple Portlets ID although code gets compiled
IPTSession ptSession = new InProcSession();
ptSession.Connect(AppSettings.PTUserName(), AppSettings.PTPassword(), null);
IPTSearchRequest ptSearchRequest = ptSession.GetSearchRequest();
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_APPS, PT_SEARCH_APPS.PT_SEARCH_APPS_CONTENT);
int[][] ar = new int[2][];
int[] int1 = new int[]{ 0, 10468 };
int[] int2 =new int[]{ 0, 23757 };
ar[0] = int1;
ar[1] = int2;
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_ASSOC_PORTLET_ID, ar);
IPTSearchQuery ptSearchQuery = ptSearchRequest.CreateBasicQuery(query, null);
IPTSearchResponse ptSearchResponse = ptSearchRequest.Search(ptSearchQuery);
return ptSearchResponse;
It will be quite useful if anyone of you can help us if Plumtree API support this. Or else we need to build another layer to search each Portlet and merge results.
Platform Details:
Plumtree Portal 5.0.4
Content Server 6.1

Hi Praveen,
I have not done portal configuration for SAP DMS. But as per the link below, you can assign multiple SAP DMS repository managers which can refer to separate content servers.

Wait for other expert comments if they can answer your query.
