title: SOLR query with raw data and union multiple facet values
body: <p>I am writing a SOLR query for faceted searching, and my fields can possibly have quotes or other bad characters in them, so I am using the raw operator to construct the query. However, if the user selects multiple facet values, I can't see how to use an OR in the query.</p>
  
  <p>For example, the following returns results for a Manufacturer of Nike:</p>
  
  <pre><code>{!raw f=Manufacturer}Nike
  </code></pre>
  
  <p>The following returns results only for a Manufacturer of Adidas:</p>
  
  <pre><code>{!raw f=Manufacturer}Nike OR {!raw f=Manufacturer}Adidas
  </code></pre>
  
  <p>And the following returns no results:</p>
  
  <pre><code>{!raw f=Manufacturer}Nike OR Adidas
  </code></pre>
  
  <p>Is there a way to do this?</p>
