-----------------------------------

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.

Attachment: SpanHighlighter-01-26-2008.patch

This patch gets rid of the separate SpanScorer test class and combines all test in HighlighterTest. Almost all of the tests are now run twice - once with the standard QueryScorer and once with the new SpanScorer.

Thanks to all for the bug fixes and contributions.

- Mark
