  <p>I am using the above code. But there seems to be some issue with the "KeywordRepeatFilter" as I am getting the error</p>

  <p>But when I removed the solr.KeywordRepeatFilter line, everything seems to work fine.
  Can anyone pls tell me what is wrong. Is the "solr.KeywordRepeatFilter" been removed from Solr 4.4 ?</p>
