Hi again Daniel et al,

I copied each line separately this time and the script now works. But it 
produces exactly the same results as it did before I inserted the extra 

That is, in my v1.5, in sub create_query I now have...

  foreach my $term (@terms) {
    $buffer = normalize($term);
    foreach my $nterm (split " ",$buffer) {
      $sterm = stem($nterm);
      # For "Match all words" just add a "+" to every term that has no 
      if ( $query->param('mode') eq 'all' && $term !~ m/^(\+|\-)/) {
         $term = '+'.$term;

(The last 3 lines, after the comment, is the added bit.) So this should 
be adding a + sign in front of every search term to create a default AND. 
But prior to this change a search on 3 terms returned 376 matches and 
after it I still get 376 matches. But if I manually type a + sign in 
front of each term I get 108 matches.

Do I need to add anything more?
