I have been involved in the Lucene implementations of Jackrabbit (and before Slide). With respect to repositories (jsr-170 / jsr-283), where the backing persistence are some database and the storage is mainly key-value's, we use Lucene to do all relational queries (a subset of xpath/sql is translated to Lucene queries). This custom Lucene implementation (see [1] for overview) can imo never be replaced by Solr afaik, the only thing it has in common with Solr is that they both use Lucene. I agree with Uri that Lucene has a much larger install base than Solr Regards Ard [1] http://jackrabbit.apache.org/index-readers.html > Cheers, > Uri >
