Assuming you are returning something like [item-description] from
your search. Something like this would work if I understand your
question correctly.

[calc]
# Set the maximum length of the string you want to display
$max_length = 25;
$out = q{[item-description]};
if (length($out) > $max_length) {
	$out = substr($out,0,$max_length);
      # In case we chopped up a word, backup to the last space
	$out =~ s/ [^ ]*$//;
      # add some ... to the end of the string
	return $out . " ..."; 
}
return $out;
[/calc]

Think this is what you want...
