I found the reason that causes this problem.
In file LuceneQueryOptimizer, there is a method called
public TopDocs optimize(BooleanQuery original,
Searcher searcher, int
numHits, String sortField, boolean reverse)
There is a block processing range query. That's the
place that prevents using range query alone.
So, I'd like to know why not to add range query into
the query variable? why not to change range query's
boost back to 1.0f (the range query boost value is set
to 0.0f in DateQueryFilter)?
Is this purpose or a bug?

smith.
