/**
* takes a search result document and processes its fields according to the

* * timestamp - converts a date field into a unix timestamp
* * serialize - uses serialize() to encode multivalue fields which then can be put out using the MULTIVALUE view helper
* * skip - skips the whole field so that it is not available in the result, useful for the spell field f.e.
* The default is to do nothing and just add the document's field to the
* resulting array.
*
* @param \Apache_Solr_Document $document the Apache_Solr_Document result document
