Using where on load records

I'm trying to display information on a page - only if the record has information in the 'content' wysiwyg editor of the record created for it, any record that does not contain information in the 'content' filed within the CMS will not be displayed. I need to apply this on the ( // load records from clients ).

Anyone have any suggestions on how to get this working?

    // search results per page
if (@$_REQUEST['searchResultsPerPage'] AND is_numeric(@$_REQUEST['searchResultsPerPage'])){
  $perPage = $_REQUEST['searchResultsPerPage'];
}
else{
  $perPage = '4';
}
  
    // load records from 'clients'
  list($clientsRecords, $clientsMetaData) = getRecords(array(
    'tableName'   => 'clients',
    'where'       => 'content',
    'perPage'     => @$perPage ? $perPage : '4',
    'loadUploads' => true,
    'allowSearch' => true,
    'orderBy'     => 'date DESC',
  ));

With what I have presently - nothing displays.
