rails：使用elasticsearch咀嚼宝石使用数据地址键入搜索

Question

我用耐嚼宝石弹力搜索。

我有LocationsIndex,mapping：

class LocationsIndex < Chewy::Index
  settings analysis: {
    analyzer: {
      folding: {
          tokenizer: "standard",
          filter:  [ "lowercase", "asciifolding" ]
        },
      sorted: {
        tokenizer: 'keyword',
        filter: ['lowercase', 'asciifolding']
      }
    }
  }

  define_type Location do
    field :name, type: 'string', analyzer: 'standard' do
      field :folded, type: 'string', analyzer:   "folding"
    end
    field :address, type: 'string', analyzer: 'standard' do
      field :address, type: 'string', analyzer: 'folding'
    end
    field :locations, type: 'geo_point', value: ->{ {lat: lat, lon: lon} }
  end

end

当我查询：

LocationsIndex::Location.query(
        multi_match: {
          query: keyword,
          fields: ["address", "address.folded" ,"name", "name.folded"]
        }
      )

数据示例：

当我使用关键字=“Vietnam”运行查询时

result :
 _id = [131,132,,133,134,135,136,137,138,139,130]  # => OK working

result :
     _id = [132,135,139]  # => Don't working ???, should have been: _id = [132,135,136,137,138,139]

与keywork=“hue”相同

result :
         _id = [132,135]  # => Don't working ???, should have been: _id = [132,135,136,137,138,139]

如何搜索包含上述单词的结果（添加类型或执行任何操作）

Answer 1

声明字段address时出错。您声明的是address.address而不是address.folded。换言之，声明应：

field :address, type: 'string', analyzer: 'standard' do
  field :folded, type: 'string', analyzer: 'folding'
end
