lemoos, Please see this question and Nick Hrycan's blog post. Note that this is highly version-dependent, so you will probably need to tweak this to your version of Lucene.

BTW, Solr has much simpler highlighting - if you have not invested a lot of time and effort in Lucene, you may consider switching to Solr.
