How to identify documents failed in a batch request?

[S G]

Hi,

I am using the following code to send documents to Solr:

        final UpdateRequest request = new UpdateRequest();
        request.setAction(UpdateRequest.ACTION.COMMIT, false, false);
        request.add(docsList);
        UpdateResponse response = request.process(solrClient);

The response returned from the last line does not seem to be very helpful
in determining how I can identify documents failed in a batch request.

Does anyone know how this can be done?

Thanks
SG
