Hi, i have attached an implementation for this issue assuming the same functionality as IS.searchAfter with no sort. Kindly review my fix and provide feedbacks. The two parameters used for paging are pageScore and pageDoc.

> There are possibly ways to improve collections of "deep paging" by passing Solr/Lucene more information about the last page of results seen, thereby saving priority queue operations.   See LUCENE-2215.
> There may also be better options for retrieving large numbers of rows at a time that are worth exploring.  LUCENE-2127.
