Why do you use such complicated stuff to build the BQ?

Term term1 =3D new Term(LuceneIndexField.SCALE, "10000");
Term term2 =3D new Term(LuceneIndexField.SCALE, "50000");
BooleanQuery bq =3D new BooleanQuery();
bq.add(new RangeQuery(term1, term1, true), BooleanClause.Occur.SHOULD);=20
bq.add(new RangeQuery(term2, term2, true), BooleanClause.Occur.SHOULD);

By the way, your code is outdated, you should better use =
NumericRangeQuery for numerics! Else RangeQuery is deprecated and =
replaced by TermRangeQuery:

String term1 =3D "10000", term2 =3D "50000";
BooleanQuery bq =3D new BooleanQuery();
bq.add(new TermRangeQuery(LuceneIndexField.SCALE, term1, term1, true, =
true), BooleanClause.Occur.SHOULD);=20
bq.add(new TermRangeQuery(LuceneIndexField.SCALE, term2, term2, true, =
true), BooleanClause.Occur.SHOULD);
