I'm not sure it does return an error on zero hits.  I think for the API
zero hits is just zero hits, and not a problem with the query or anything
else.

This is what SWISH::API docs show:

           # then in a loop
           my $results = $search->Execute( $query );

           # always check for errors (but aborting is not always necessary)

           $swish->AbortLastError
               if $swish->Error;

           # Display a list of results

           my $hits = $results->Hits;
           if ( !$hits ) {
               print "No Results\n";
               return;  /* for example *.
           }

Although I doubt you want to use C-type comments in Perl! ;)
