Use the where method:
User.where(id: 14000..14500)

You can do it like this too:
User.find_by_id(14000..14500)

Try this also
User.find((start..end).to_a)
Ex -
User.find((14000..14500).to_a)

You can use range definition for scoped:
User.find(1) # returns the object for ID = 1
User.find([1])
User.find(1, 2, 9) # returns an array for objects with IDs in (1, 2, 9)
User.find([1, 2, 9])
User.scoped(:conditions => { :id => 1..9})
