What version of Lucene are you using? I don't think the form
b.add(query, false, false) is current.
Be that as it may, I'm not quite sure what you mean by
filter. If I'm reading your intent correctly, wouldn't requiring
each non-empty field accomplish what you want? Which would
be something like
b.add(query, BooleanClause.MUST);
