title: Solr: exclude parts of url
body: <p>I have a field url in schema.xml. I need to separate my search results based on this field. </p>
  
  <p>For example </p>
  
  <ul>
  <li>in one search I want results of <strong>www.example.com/part1/</strong> actually all results that have this prefix. </li>
  <li>for another search I want results from <strong>www.example.com</strong>, but without all documents containing <strong>/part1/</strong> in their url. </li>
  </ul>
  
  <p>How can I achieve this? fq doesn't accept special characters and I don't want to split content with NGramFilterFactory, so that this behaviour should be only at search-time.</p>
