title: Spring data elasticsearch repository "StartingWith" throws InvalidDataAccessApiUsageException when searching for string with spaces
body: <p>I have a repository method that does a "starts with" (prefix) query on field <code>userAccount.userName</code>. When I search for string without space, it returns proper results. But when I search for strings with space in it, it throws an exception.</p>
  
  <p>My repository method:</p>
  
  <pre><code>public List&lt;EsUser&gt; findByUserAccountUserNameStartingWith(String term);
  </code></pre>
  
  <blockquote>
    <p>Search String: Tom Cruise</p>
  </blockquote>
  
  <p>Exception:</p>
  
  <blockquote>
    <p>org.springframework.dao.InvalidDataAccessApiUsageException: Cannot
    constructQuery '*"Tom Cruise"'. Use expression or multiple clauses
    instead.</p>
