title: solr field replace in the query
body: <p>I have a query like that where "brand" is in my schema:</p>
  
  <pre><code>select?rows=1&amp;start=0&amp;sort=price+asc&amp;q=brand:sony&amp;qt=for-search&amp;wt=xml
  </code></pre>
  
  <p>But I want to do this instead:</p>
  
  <pre><code>select?rows=1&amp;start=0&amp;sort=price+asc&amp;q=brand_name:sony&amp;qt=for-search&amp;wt=xml
  </code></pre>
  
  <p>and define something like brand_name:brand in my Solr config. Is there a way to do that ?
  Thank you</p>
