Alexander Schäfer commented on CLEREZZA-388:
--------------------------------------------
I'm currently pursuing a way to implement faceted search in clerezza via Solr,
as Solr provides a nice interface and management system for lucene indices. As
far as I understand, CRIS is composed of three parts, a way to subscribe to a
graph, a simple query system and the actual indexing via Lucene. Would it make
sense to modularize all features? This would allow me replace the query system
with a SPARQL based one once it is performant enough, and the indexing system
with Solr.
