Subject Re: [jira] [Closed] (JSPWIKI-498) Performance Issues with Lucene Index
Date Mon, 07 Jan 2013 08:20:20 GMT
Hi Glen,

In reading over the entire list of comments on the issue I think my input would
at this point not be of value -- it seems the problem was in the
LuceneHighlighter,
and that this would be dealt with separately via a patch. And as already noted,
that has its own issues...
