We use Solr to inject non-nutch crawled Lucene documents into the
main Nutch index. This works fine.. we can search (not using the
nutch searcher) both nutch docs and the solr injected docs with one
query.
However, I would like to use the IndexMerger for merging successive
Nutch crawls. If one of the index directories we give bin/nutch merge
has Solr-generated Lucene docs in it, we get:

Any way around this?
