title: Elastic search returning incorrect results
body: <p>I am using elastic search with laravel.</p>
  
  <p>When I pass value "abbas" to $q, elastic search returns results matching with abbas as well as robert. 
  Query is:</p>
  
  <p>$q   = Input::get('q');</p>
  
  <pre><code>    $pararm = [            
          'bool'=&gt;[
              'must'=&gt;[
                  'wildcard'=&gt;[
                      '_all'=&gt;[
                          'value'=&gt;"*".strtolower($q)."*"                                   
                      ]
                  ]
              ]
          ]
      ];
  
      $arrobjUsers    = collect(User::searchByQuery($pararm))-&gt;keyBy('id');
  </code></pre>
  
  <p>Please let me know where I am wrong?</p>
