------------------------------------------
Mark,
I added a few lines of code to the WeightedSpanTermExtractor.extract method to
handle DisjunctionMaxQuery instances. I didn't take the time to make a patch
against your new version but the code is pretty simple:
{code}
...
} else if (query instanceof DisjunctionMaxQuery) {}}
Map disjunctTerms = new HashMap();
for (Iterator iterator = ((DisjunctionMaxQuery) query).iterator();
iterator.hasNext();) {
extract((Query) iterator.next(), disjunctTerms);
}
terms.putAll(disjunctTerms);
} else {
...
{code}
> Extend contrib Highlighter to properly support phrase queries and span queries

> 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.
