How about making excerpt_field part of the constructor? Then we have  
this:

   my $simple = KinoSearch::Simple->new(
      path => '/path/to/index',
      language => 'en',
      excerpt_field => 'body',
   );
   $simple->search(
      query         => 'foo bar',
   );
   while ( my $hit = $simple->fetch_hit ) {
      print qq|
         <p>
            <strong>$hit->{title}</strong><br />
            | . $simple->create_excerpt . qq|
         </p>
         |;
   }

But I suppose this is starting to become KinoSearch::NotSoSimple, so  
maybe we should forget about it.
