Shawn Heisey commented on SOLR-3950:
------------------------------------
Pinging on this. The consensus among the Really Smart People (tm) seems to be
that a wrapper implementation needs to be available for Solr that wraps another
postings format in the BloomFilter, such as Lucene42 (if that even exists yet).
If someone can point me at code for a similar wrapper implementation and tell
me which class I'd need to extend (and/or interface I'd need to implement), I'm
happy to try to create the patch for this issue. I understand the general idea
but I would need a prod in the right direction.
