title: Solr booster by date range relevance
body: <p>I am searching by date range by relevance.
  Using this URL :</p>
  
  <pre><code>(((publicationdate:[1919-12-31T00:00:00.000Z TO 1977-12-31T23:59:59.999Z])^1000)     OR((publicationdate:[1978-01-01T00:00:00.000Z TO 2014-12-31T23:59:59.999Z]))^1)
  </code></pre>
