    Attachment: spanhighlighter_24_January_2008.patch

Relocated the fir.close() to after the extract(bq, terms) call.  Problem had 
manifested itself as a org.apache.lucene.store.AlreadyClosedException, but 
should be fixed via this patch.

> This patch adds a new Scorer class (SpanQueryScorer) to the Highlighter 
> package that scores just like QueryScorer, but scores a 0 for Terms that did 
> not cause the Query hit. This gives 'actual' hit highlighting for the range 
> of SpanQuerys and PhraseQuery. There is also a new Fragmenter that attempts 
> to fragment without breaking up Spans.
> See http://issues.apache.org/jira/browse/LUCENE-403 for some background.
> There is a dependency on MemoryIndex.
