/**
   *  This method specifically creates a search service stub to do search by mediaType as the existing admin service uses a http
 *    request parameters to obtain the media type. But in this particular case the page gets directed from the component xml and
 *    hence cannot add pre defined request params there. And to keep the search admin service structure as it is, thus this bundle creates
 *    a separate client to access the search stub.
