+ == Consider Using a Filter ==

+ Building a Query that for a number (or a range of numbers) is just like building a Query for a word -- it involves scoring based on the frequency of that word (or number) in the index which isn't usually what people want.  So you may want to consider "Filtering" using the RangeFilter class instead.  It can be a lot more efficient then using the RangeQuery class because it can skip all of the score related issues.
