> I did look into sorting an index after it was created and found that with some smallish modifications we can actually allow that by piggibacking on SortingLeafReader and addIndices in a pretty straight-forward and simple way. With some smallish modifications / fixes to SortingLeafReader we can just merge and unsorted index into a sorted index using a fresh index writer.
