The flat function interface is deprecated.  Also, use symbolic constants
rather than the numbers that happen to currently be equivalent.  So
instead write:

         $query_parser = new queryparser();
 
         //set the stemmer and turn on the stemming strategy
         $query_parser->set_stemmer($stemmer);
         $query_parser->set_stemming_strategy(QueryParser_STEM_SOME);

What's $append?  It's almost inevitably a mistake to attempt to
manipulate the user's input before feeding it to the QueryParser.
If you want to add filters, etc then construct a new Query object
from the Query object that the QueryParser builds.

Not from the information given - everything looks plausible.  Try adding
this to see what $query is:

    echo $query->get_description()."\n";

If that looks OK, then use "delve" to see what terms are actually in the
database.
