    Description

      If using IndexBasedSpellChecker and spellcheck.q is empty the following exception occurs. The default DirectSolrSpellChecker doesn't have this since there is a minimum size of tokens checked. The exception is from Lucene, but opening this in Solr for now since it is exposed through Solr.
