title: Default search on all fields
body: <p>I can only get Solr to work when I include a field in the query, for example:</p>
  
  <pre><code>http://localhost:8983/solr/collection1/select?q=lastname:johnson
  </code></pre>
  
  <p>The above query returns approximately 18 results.</p>
  
  <p>Shouldn't it be possible to use Solr (/Lucene) without specifying the field? Such as:</p>
  
  <pre><code>http://localhost:8983/solr/collection1/select?q=johnson
  </code></pre>
  
  <p>I also tried adding the fields list:</p>
  
  <pre><code>http://localhost:8983/solr/collection1/select?q=johnson&amp;fl=cus_id%2Cinitials%2Clastname%2Cpostcode%2Ccity
  </code></pre>
  
  <p>But all these queries return zero results.</p>
  
  <p>These are the fields from my schema.xml:</p>
  
  <pre><code>&lt;field name="cus_id" type="string" indexed="true" stored="true"/&gt;
  &lt;field name="initials" type="text_general" indexed="true" stored="true" /&gt;
  &lt;field name="lastname" type="text_general" indexed="true" stored="true"/&gt;
  &lt;field name="postcode" type="string" indexed="true" stored="true" /&gt;
  &lt;field name="city" type="text_general" indexed="true" stored="true"/&gt;
  </code></pre>
  
  <p>I don't know what else to try. Any suggestions?</p>
