eZfind and packed data

Thursday 17 September 2009 6:56:55 am

Hi,
I would like to generate a xml file with the meta-data of my object
Here is the code :

...
   foreach ( $currentVersion->contentObjectAttributes() as $attribute )
    {
        $classAttribute = $attribute->contentClassAttribute();
        if ( $classAttribute->attribute( "is_searchable" ) == 1 )
        {
            // Fetch attribute translations
            $attributeTranslations = $attribute->fetchAttributeTranslations();

            foreach ( $attributeTranslations as $translation )
            {
                // here is the text !!
                $text =$translation->metaData(); 
            }
        }
     }
...

When I index an pdf file using ezfind & solr, my "metadata text" is packed.
I have only some #####

How can I my unpacked text ? Do i have to some a request to solr ?
Any help is welcome :)
