Nope, I'm afraid I can't. Because I don't really understand it in detail, the wizard from Germany (Uwe) put it in place....
But here's a great place to start if you want to dive deep: https://hudson.apache.org/hudson/job/Lucene-trunk/javadoc/all/org/apache/lucene/search/NumericRangeQuery.html?is-external=true But with only 1,000 distinct values, I don't think you really need to pursue this very far except for curiosity's sake. Just go with 4 as the page above suggests....
