Hi Vijayaragavan, did you apply a patch for grouping in Solr 3.1? It is available out of the box since 3.3. Also, the result from grouping will not look exactly like you are expecting, as results with the same value in the grouping field (in this case, thread_id) will be collapsed into one group. You can get many documents per group though (with group.limit) but the output will not be like regular results.
