title: Search functionality not working using ID field input
body: <p>I am using the search plugin on <a href="https://github.com/cakedc/search" rel="nofollow">https://github.com/cakedc/search</a>. I am trying to search for records using the ID field only, that is if i type in 1 on my form input it must show a record with user ID 1. The challenge that i am having now is when i specify that the input should be the id field, the input field for the search functionality disappears on my index view, strange thing is when i specify a different field name the input field shows.</p>
  
  <p><strong>Below is my code for my Model</strong></p>
  
  <pre><code>public $actsAs = array('Search.Searchable');
  
  public $filterArgs = array(
  'id' =&gt; array('type' =&gt; 'like', 'field' =&gt; 'ItSupportRequest.id'),
  );
  
  public function findByTags($data = array()) {
  $this-&gt;Tagged-&gt;Behaviors-&gt;attach('Containable', array('autoFields' =&gt; false));
  $this-&gt;Tagged-&gt;Behaviors-&gt;attach('Search.Searchable');
  $query = $this-&gt;Tagged-&gt;getQuery('all', array(
  'conditions' =&gt; array('Tag.name'  =&gt; $data['tags']),
  'fields' =&gt; array('foreign_key'),
  'contain' =&gt; array('Tag')
  ));
  return $query;
  }
  
  public function orConditions($data = array()) {
  $filter = $data['filter'];
  $cond = array(
  'OR' =&gt; array(
  $this-&gt;alias . '.id LIKE' =&gt; '%' . $filter . '%',
  ));
  return $cond;
  </code></pre>
  
  <p>}</p>
  
  <p><strong>and here is my controller code.</strong></p>
  
  <pre><code>public $components = array('Search.Prg');
  
  public $presetVars = true; // using the model configuration
  
  public function find() {
  $this-&gt;Prg-&gt;commonProcess();
  $this-&gt;paginate['conditions'] = $this-&gt;ItSupportRequest-&gt;parseCriteria($this-&gt;passedArgs);
  $this-&gt;set('articles', $this-&gt;paginate());
  }
  </code></pre>
  
  <p><strong>and in my index.ctp file i have this code.</strong></p>
  
  <pre><code>&lt;?php 
  echo $this-&gt;Form-&gt;create('ItSupportRequest', array(
  'url' =&gt; array_merge(array('action' =&gt; 'find'), $this-&gt;params['pass'])
  ));
  echo $this-&gt;Form-&gt;label('Query ID:') . "&lt;br/&gt;";        
  echo $this-&gt;Form-&gt;input('name', array('div' =&gt; false, 'label' =&gt; false));
  
  echo $this-&gt;Form-&gt;submit(__('Search'), array('div' =&gt; false));
  echo $this-&gt;Form-&gt;end();
  ?&gt;  
  </code></pre>
  
  <p>Thanks in advance.</p>
