How is a null value handled in a given range type , ie if doc has field with gte=null and lte=5 and a query looks for the value 4 in the range, will it bring up the doc with the given ranges or not?
if you indexed a document where a field is either missing or set to null
, then it is not part of your range. Only document that have this field set, will be part of the range.
You could use the null_value feature in the mapping to change this behaviour.

that doesn't answer how a range type is handled when one of the values is null, ie gte=null & lte=500 and do a search on field for 400 inside the range, what happens?
