Do you think it would be possible to integrate Apache Solr into PW? It seems like all major CMS have plugins for this. In the office I work I am the only one using processwire (the others use ez Publish), and whenever I want to convince them to use PW they complain that without out Solr integration they don't want to. Personally I am happy with the speed and results of the pw api.
I have no idea how complicated it would be to build a SolrModule, but still I want to ask. It would be a good marketing keyword for sure
