Shalin Shekhar Mangar resolved SOLR-5347.
-----------------------------------------

       Resolution: Invalid
    Fix Version/s:     (was: 4.6)
                       (was: 5.0)

I was mistaken. The 'start' and 'rows' parameter are only for debug mode. They aren't supported in non-debug mode.

> The 'rows' param is initialized to Long.MAX_VALUE by default. Therefore when 'start' parameter is specified and DocBuilder does the following check:
> {code}
> if(importStatistics.docCount.get() > (reqParams.getStart() + reqParams.getRows())) break;
> {code}
> The R.H.S. overflows and the condition evaluates to true. The end result is that no documents are ever indexed.
