弹性搜索排序的正确方法是什么？

Question

I am using elasticsearch with a ruby application via Tire gem. Here is my index

mapping do
  indexes :title
  indexes :views_count, type: 'integer'
  indexes :created_time, type: 'date'
end

And my query:-

News.tire.search load: true do 
  query {all}
  sort { by :views_count, 'desc'}
end

This is pretty good and looks it will be works well. However, There is unexpected result. It treats numbers as strings. That means it will consider '33' less than '4'. I want to tell elasticsearch to treat them as integers not strings.

And the same thing is happening with created_time but I did not notice the pattern it sorts with. I think I should pass type or something. So, any body can help me?

Thank you in advance.

我的错误是我只更新索引，而不更新索引的映射，因为在创建映射之前发现类型参数之前，存在映射。
