rails : type search with data address use elasticsearch chewy gem

Question

I use chewy gem elasticsearch .

I have 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

when i query:

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

data sample :

{ "took" : 2, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 10, "max_score" : 1.0, "hits" : [ { "_index" : "locations", "_type" : "location", "_id" : "131", "_score" : 1.0, "_source":{"name":"Việt Nam","address":"Việt Nam","locations":{"lat":16.9054,"lon":106.576}} }, { "_index" : "locations", "_type" : "location", "_id" : "136", "_score" : 1.0, "_source":{"name":"Quan truong Ngo Mon","address":"23/8, Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4669,"lon":107.58}} }, { "_index" : "locations", "_type" : "location", "_id" : "132", "_score" : 1.0, "_source":{"name":"Thừa Thiên Huế","address":"Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4674,"lon":107.591}} }, { "_index" : "locations", "_type" : "location", "_id" : "137", "_score" : 1.0, "_source":{"name":"Phu Van Lau","address":"23/8, Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4655,"lon":107.581}} }, { "_index" : "locations", "_type" : "location", "_id" : "133", "_score" : 1.0, "_source":{"name":"Ha Noi","address":"Ha Noi, Việt Nam","locations":{"lat":16.4674,"lon":107.591}} }, { "_index" : "locations", "_type" : "location", "_id" : "138", "_score" : 1.0, "_source":{"name":"Cau gia Vien","address":"Le Duan, Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4601,"lon":107.571}} }, { "_index" : "locations", "_type" : "location", "_id" : "134", "_score" : 1.0, "_source":{"name":"TP Ho Chi Minh","address":"TP Ho Chi Minh, Việt Nam","locations":{"lat":16.4674,"lon":107.591}} }, { "_index" : "locations", "_type" : "location", "_id" : "139", "_score" : 1.0, "_source":{"name":"Chua thien Pagoda","address":"Kim Long, Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4537,"lon":107.545}} }, { "_index" : "locations", "_type" : "location", "_id" : "130", "_score" : 1.0, "_source":{"name":"Việt Nam","address":"Việt Nam","locations":{"lat":16.9054,"lon":106.576}} }, { "_index" : "locations", "_type" : "location", "_id" : "135", "_score" : 1.0, "_source":{"name":"Dai Noi Hue","address":"23/8, Thừa Thiên Huế, Việt Nam","locations":{"lat":16.4698,"lon":107.577}} } ] } }

when i run query with keyword = "viet nam"

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

but i when run query with keywork = "thua thien hue"

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

Same with keywork = "hue"

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

how search results that contain the above word (add type, or do anything)

You have an error when declaring field address. You are declaring address.address instead of address.folded. In other words, the declaration should be:

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

rails : type search with data address use elasticsearch chewy gem
