Subject Re: Highlight Wildcard Queries
Date Tue, 25 Jan 2011 19:43:51 GMT
Hi Wulf,

Check the http://www.lucidimagination.com/blog/2009/06/08/bringing-the-highlighter-back-to-wildcard-queries-in-solr-14/
this may help. I do not know what of Mark's changes are in Lucene 3.x,
but most likely you
will just need to set a proper RewriteMethod for the MultiTermQuery somewhere.
