Hi all,

I also implemented an Highlight functionality based on Maik Schreiber's code
and
modified the Lucene source. I agree with Peter that it will be great to have
this changes done
in the Lucene core code.

The only difference in my functionality is that query.getTerms() returns
both TermQuery and PhraseQuery object, so that the Highlighter does not
split compound words.

I was also wondering : is there a reason why Query object do not have a
clone() method?
Do you think it could be useful?

Julien
