Multilingual Search

[ts90]

Hi,

I am working on a project to perform multilingual full-text search using Elasticsearch. one field can contain a word combination of different languages or transliteration. for example in the English text may contain Armenian words. or Russian words in the Armenian text. and i am trying now to configure text analysis with language analyzer.
in my case don't know what language it is before indexing.

  "settings": {
    "analysis": {
      "filter": {
        "armenian_stop": {
          "type": "stop",
          "stopwords": "_armenian_"
        },
        "armenian_keywords": {
          "type": "keyword_marker",
          "keywords": [
            "օրինակ"
          ]
        },
        "armenian_stemmer": {
          "type": "stemmer",
          "language": "armenian"
        },
        "russian_stop": {
          "type": "stop",
          "stopwords": "_russian_"
        },
        "russian_keywords": {
          "type": "keyword_marker",
          "keywords": [
            "пример"

      },
      "analyzer": {
        "rebuilt_armenian": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",

          ]
        },
        "rebuilt_russian": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "russian_stop",
            "russian_keywords",
            "russian_stemmer"
          ]
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "age": {
        "type": "integer"
      },
      "email": {
        "type": "keyword"
      },
      "name": {
        "type": "text",
        "fields": {
          "ar": {
            "type": "text",
            "analyzer": "rebuilt_armenian"
          },
          "ru": {
            "type": "text",
            "analyzer": "rebuilt_russian"
          }
        }
      },
      "location": {
        "type": "geo_point"
      }
    }
  }
}

query:
and as far as I understand it is necessary to search for specific fields, if you search for example by "name" then the standard analyzer will work
Am I doing everything right?

{
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "fields": [ "name.ar", "name.ru"],
            "query": "ներմուծված"
          }
        }
      ],
      "filter": [
        {
          "geo_distance": {
          "distance": "25km",
          "location": {
            "lat": 40.79420000	,
            "lon": 43.84528000
          }
        }
        }
      ]
    }
  }
}
