What are the correct keys for sub controller

Question

I have a file that is located: app/controllers/api/v1/users/searches_controller.rb

This file starts as following:

module Api
  module V1
    module Users
      class SearchesController < ActionController::API

And I have this code:

I18n.t('.search')

When I say

i18n-tasks missing

It wants to put my key like thins: .search

Which is not in the way I would like which is

api:
  v1:
    users:
      searches_controller:
      .......

When I say:

t('.search')

I get an error with: NoMethodError - undefined methodt' for ....`

But i18n-tasks missing gives me the keys as following:

api:
    v1:
      users:
        searches:
          users_with_email_or_username:
          .......

Am I doing something wrong or?
