Correct.

If I explicitly specify excerpt_length:

my $hl             = Lucy::Highlight::Highlighter->new(
   searcher       => $searcher,
   query          => $query_compiler,
   field          => 'site',
   excerpt_length => 60,
);

...and the field content is longer than 60, then

$page_highlighter->create_excerpt($hit);

returns '...'.

Content which is short than 60, returns the highlighted excerpt as expected.

If I comment out "excerpt_length => 60," above, then it returns the full
non-truncated excerpt with highlighting as expected.

Some >60char samples which return &#8230;/"...", searching for [iol.co.za] or
[news24.com] (brackets are mine):

The following return double-ellipses ("......" - &#8230;&#8230;), searching
for [adsl mweb.com]:

Hope that helps.
