elasticsearchHow can I use Elasticsearch and Hunspell to add Russian language support to my software?

To add Russian language support to your software using Elasticsearch and Hunspell, you need to do the following:

1. Install the Elasticsearch Russian Language Analyzer plugin.

2. Install the Hunspell Russian dictionary on your system.

3. Configure the Elasticsearch index to use the Russian language analyzer and Hunspell dictionary. This can be done using the following example code:

PUT /myindex
{
  "settings": {
    "analysis": {
      "filter": {
        "my_russian_hunspell": {
          "type": "hunspell",
          "locale": "ru_RU",
          "dedup": true
        }
      },
      "analyzer": {
        "my_russian_analyzer": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "my_russian_hunspell"
          ]
        }
      }
    }
  }
}

4. Create a mapping for the fields in your index that should be analyzed using the Russian language analyzer. This can be done using the following example code:

PUT /myindex/_mapping
{
  "properties": {
    "title": {
      "type": "text",
      "analyzer": "my_russian_analyzer"
    }
  }
}

5. Index documents in your Elasticsearch index using the Russian language analyzer. This can be done using the following example code:

POST /myindex/_doc
{
  "title": "Это тестовый документ"
}

6. Query the indexed documents using the Russian language analyzer. This can be done using the following example code:

GET /myindex/_search
{
  "query": {
    "match": {
      "title": "тестовый"
    }
  }
}

The output of this query should be the document you indexed in step 5.
