This means there are effectively two copies of the same information.  We

would like to use the markup instead.  Can Lucene handle this (I will
check)?

I index configuration, metadata xml and content pieces with lucene. When doing the search I get the hits and take field values and form that into XML to be styled by XSL (resulting in something similar to what you have, I think). You can even index your XSL offline for your own use :). Anyway, using this:


QueryHighlightExtractor qhe = new QueryHighlightExtractor(query,
                                    new StandardAnalyzer(),
                                    "<span class='highlight'>",
                                    "</span>");

will do what you want.

A while ago I did searches with XSL and found it to be extremely resource intensive, in our case. Indexing with Lucene is extremely fast and searching that index is extremely fast and light on resources. There are many types of searches that are ridiculously hard with XSL (i.e. fuzzy queries). Check out the contributions and sandbox on the lucene site - you can probably have something up and running within a day.
