title: Solr only search in default field
body: <p>I can't search in other field than the default. With q=field:search doesn't return nothing (but documents exists obsviouly). Also didn't find it with defType=dismax. </p>
  
  <p>In the schema.xml I have the field with indexed="true" and stored="true" just like the default one.</p>
  
  <p>What I am missing ? </p>
  
  <p>Thanks in advance.</p>
