  <p>I want to make a query that will get a string and find</p>
  
  <p>if this string equals (or part of) - "first_name (space) last_name"</p>
  
  <p>for example, a good queries will be:</p>

  <pre><code>String selection = "first_name" + " " + "last_name" + " LIKE '" + GIVEN_STRING + "%'";
  </code></pre>
  
  <p>but without luck</p>
