That sounds reasonable. If you implement this, please send a patch.

Yes, it might in some cases. For the cases I have in mind, the
different indexes would be written at different times, and this would
not be useful. But if you do this differently, please contribute a
ParallelWriter.

Thanks for catching that. I just fixed it.

Doug, is this something you plan to fix before 1.9?

It seems the IllegalArgumentException is never thrown, because the
"readers" variable is never modified?
Unless I'm missing something, this code should throw an exception if the
indexes have different sizes:
IndexReader ir1 = IndexReader.open("/tmp/testindex1");
IndexReader ir2 = IndexReader.open("/tmp/testindex2");
ParallelReader pr = new ParallelReader();
pr.add(ir1);
pr.add(ir2);
Regards
Daniel
