I'm having terrible problems with Alfresco 4 & Solr.When I run a search, it seems that only files from the default demo site are returned. This would indicate to me that solr isn't indexing. However, when checking https://localhost:8443/solr/alfresco/admin/replication/index.jsp (from the server hosting Alfresco) I see that the size of the local index is increasing. I am seeing tons of errors as described here https://forums.alfresco.com/en/viewtopic.php?f=9&t=41569 (although the errors must be particularly unusual as noone has replied yet)Also, as I've just noticed, looking at the solr index folder at 
\Alfresco\alf_data\solr\workspace\SpacesStore\index, none of the files have been modified since the server was last started 40 minutes ago (by checking each files last modified attribute). The replication page here: https://localhost:8443/solr/alfresco/admin/replication/index.jsp however suggests that Index version is incrementing and the size growing.Finally, trying to add a tag to a calendar event by selecting 'choose from popular tags on this site' results in a message 'Failure: Cannot load tags from the server (connection down?)'I wonder if anyone would be kind enough to run their eyes across my configuration and tell me whether or not the see anything wrong with it please? I'm really struggling with this.
