Re: docid sort not supported for Solr4?

[Marcin Rzewucki]

Hi,

It does not work for distributed search:
org.apache.solr.handler.component.ShardFieldSortedHitQueue.getCachedComparator(ShardDoc.java:193)
...
    case DOC:
      // TODO: we can support this!
      throw new RuntimeException("Doc sort not supported");
...

Try to sort by unique ID.
Regards.
