Is it possible to search over *_encrypted columns?

I used the model from README.md.

class Person < ActiveRecord::Base
  include Vault::EncryptedModel
  vault_attribute :ssn
end

person = Person.new
person.ssn = "123-45-6789"
person.save #=> true
person.ssn_encrypted

And it doesn't works

Person.where(ssn: "123-45-6789")

or

Person.find_by(ssn: "123-45-6789")
