New Zend Framework 0.8.0

The new query analyzer added in 0.8.0 tokenizes all fields whether they are keyword fields or not.
If you use keyword fields you need to parse the incoming query and use the api directly to specify
a keyword query.

something like this:

$q = new Zend_Search_Lucene_Search_Query_Boolean();
$term = new Zend_Search_Lucene_Index_Term($parts[1], 'messageid');
$keywordQuery = new Zend_Search_Lucene_Search_Query_Term($term);
$q->addSubquery($keywordQuery, true /* required */);     

It does seem to run faster, but queries with excessively large hits still use up a ton of php memory.
