Hi , I have build mediawiki with EnhancedRetrieval. When I search a existing item , it worked well. But when I search a non existing one , it reported this: ********************************************************************************** *Could not connect to SOLR Server yet. Faceted Search will not work yet. Expecting to find SOLR Server at http://192.168.160.56/extensions/EnhancedRetrieval/includes/FacetedSearch/so.... Possibly your firewall is blocking the SOLR * * ********************************************************************************** * I guess it should report something like "Sorry , no documents match "THE STRING" ...". So where is my problem? Thanks.
