title: How can you emulate a Solr "more like this query" with Postgresql full text search?
body: <p>I'd like to emulate this type of Solr query:</p>
  
  <p><a href="http://wiki.apache.org/solr/MoreLikeThis" rel="noreferrer">http://wiki.apache.org/solr/MoreLikeThis</a></p>
  
  <p>with PostgreSQL using its full text search facility.</p>
  
  <p>Is there a way to do something like a "more like this" query with pure postgres?</p>
