我有国家列表，我希望用户能够按县对结果进行排序。所以我有这个帮手：

def facets_for model, field
ul = ""
links = ""
model.facets[field]['terms'].each do |facet|
  links << content_tag('li') do
    link_to("#{facet['term']} #{facet['count']}", params.merge(field => facet['term']))
  end
end
ul << content_tag("ul", class: field) do
  links.html_safe
end
ul.html_safe

结尾

在模型中：

class model
 ....
mapping do 
 indexes :country do
   indexes :name, :type => :string, index: "not_analyzed"
 end
end




def self.search params
  ...
  filter :term, destination: params[:destination] if params[:destination].present?
  facet("destination") {  terms 'country.name' }
  ...
end

但

方面['术语']

始终以小写形式返回国家/地区名称。我可以用 Country.find(facet).name 做到这一点，但我认为这是不必要的。有什么方法可以存储与字段中相同的字符串值？

我的映射：

  {
      "wishes" : {
        "wish" : {
          "properties" : {
            "body" : {
              "type" : "string"
            },
            "country" : {
              "properties" : {
                "name" : {
                  "type" : "string"
                }
              }
            },
            "country_id" : {
              "type" : "string"
            },
            "created_at" : {
              "type" : "date",
              "format" : "dateOptionalTime"

      }
    } ... }}}

Your mapping is not created right, you can try to reindex your data.

Model.index.delete               # to delete index with bad mapping
Model.create_elasticsearch_index # this should create index with mapping defined in Model

And after that you can try to run Model.import again.
