title: Search A / B or "A / B" or A/B in Alfresco 4.2d have issues
body: <p>I have a custom model in which I have a property having following constraint :</p>
  
  <pre><code>&lt;constraint name="abc:customList" type="LIST"&gt;
         &lt;title&gt;Custom List&lt;/title&gt;
           &lt;parameter name="allowedValues"&gt;
              &lt;list&gt;
                &lt;value&gt;&lt;/value&gt;
                 &lt;value&gt;ABC&lt;/value&gt;
                 &lt;value&gt;A / B&lt;/value&gt;
                 &lt;value&gt;A/B&lt;/value&gt;
               &lt;/list&gt;
           &lt;/parameter&gt;
           &lt;parameter name="caseSensitive"&gt;&lt;value&gt;true&lt;/value&gt;&lt;/parameter&gt;
        &lt;/constraint&gt;
  </code></pre>
  
  <p>and I have created various documents having different value of above property.</p>
  
  <p>I have created a custom search form on which there are some drop-down list. when I search A / B, It gives no result but If I searched A/B it works.
  Also when I searched "A / B" it also work.</p>
  
  <p>This search functionality was working fine in Alfresco 4.2.c for all cases.</p>
  
  <p>I am not able to identify why this is not working in Alfresco 4.2.d</p>
