When "facet.missing" parameter is set to "true" Solr is returning response
containing "int" element with no "name", which possibly causes the Solrj
parsing problem. Sample server response may look like:
<lst name="genre">
<int name="rock">5559</int>
<int name="soul">5547</int>
<int name="punk">5412</int>
<int>0</int>
</lst>
