Hi, I am using SOLR 1.4.1. When I search for empty string in a string field, q=tag_facet:"", it return documents with values in tag_facet. When I use the same query q=tag_facet:"", in SOLR 3.4, it is returning only documents with "" string in tag_facet. SOLR 3.4 works as expected. I just want to know whether it is an issue in SOLR 1.4.1. Please advise.
