title: Grails searcheble don't use field during fulltext search
body: <p>Domain (just simple example):</p>
  
  <pre><code>class House {
  String address
  String region
  Long price
  static searchable = { only = ['address', 'price', 'region'] }
  } 
  </code></pre>
  
  <p>I want to search by address with price selector</p>
  
  <p>Search query is:</p>
  
  <pre><code>"${address} AND price: [100 TO 1000]"
  </code></pre>
  
  <p>But if address='500' in search result will be Houses with price 500. I need to find house for address only by House.address + House.region</p>
