SearchMapping has a dependency on Solr's analyzer package which was optional in 3.1. The current configuration design makes mandatory as the SearchMapping is now used by the SearchFactoryImpl. Three solutions: - make the analyzer optional dependency mandatory - make SearchMapping reflexively used in SFI to avoid the mandatory dependency on non programmatic model users - rethink SearchMapping to avoid the dependency Either 1 or 3 look viable to me. I don't believe in 2. Any proposal?
