sharding - Is it possible to query for a range of hashes of a hashed indexed key in mongodb? -


i have hashed based sharding enabled key "userid" in mongodb collection. possible documents hashed values of "userid" between, let's say, "abcd" , "cdef"?

thanks!

one way found use following query:

db.mycollection.find({ "$and": [   {_id: {"$gt": -5012941854059245285}},    {_id : {"$lt": -4712634714892678072}} ]}).hint({_id: "hashed"})

where long numbers hashed values of _id. works me, best way of doing so? can sure work upcoming releases of mongodb?
