Possibly somewhat unusual question: I'm looking for a way to query the number of *lucene documents* from within Solr. This can be different from the number of Solr documents (because of unmerged deletes/updates/ etc).
As a bit of background; we recently found this lovely little error message in a Solr log, and we'd like to get a bit of an early warning system going :-) > Too many documents, composite IndexReaders cannot exceed 2147483647 If no way currently exists, I'm not adverse to hacking one in, but I could use a few pointers in the general direction. As an alternative strategy, I guess I could use Lucene to walk through each index segment and add the segment info maxDoc values. But I'm not sure if that would be a good idea. Thanks a bunch, - Bram
