title: Limiting the output from MoreLikeThis in Solr
body: <p>I'm trying to use MoreLikeThis to get all similar documents but not documents with a specific contenttype.</p>
  
  <p>So the first query needs to find the one document that I want to get "More Like This" of - and the second query needs to limit the similar documents to not be pdf's (-contenttype:pdf)</p>
  
  <p>Does anyone know if this is possible?</p>
  
  <p>Thanks</p>
