It sounds like you need to pad your numbers with leading zeroes, i.e. use the same type of encoding as is required by RangeQuery's. If you query with 000005 instead of 5 do you get what you expect? If all your document id's are fixed length, then string comparison will be isomorphic to integer comparison.
