Oops. I was thinking solr.
How about this, to find docs that don't have a value in the weight field?
TermRangeQuery trq = new TermRangeQuery("weight", null, null, true, true
);
BooleanQuery bq = new BooleanQuery();
bq.add(new MatchAllDocsQuery(), BooleanClause.Occur.MUST);
bq.add(trq, BooleanClause.Occur.MUST_NOT);
