{
  "mappings": {
    "properties": {
      "content": {
        "type": "text",
        "analyzer": "hungarian"
      }
    }
  }
}

{% include copy-curl.html %}

Stem exclusion

You can use stem_exclusion with this language analyzer using the following command:

PUT index_with_stem_exclusion_hungarian_analyzer
{
  "settings": {
    "analysis": {
      "analyzer": {
        "stem_exclusion_hungarian_analyzer": {
          "type": "hungarian",
          "stem_exclusion": ["hatalom", "jóváhagyás"]
        }
      }
    }

Hungarian analyzer internals

  • stemmer (Hungarian)

          "type": "stop",
          "stopwords": "_hungarian_"
        },

        }
      },
      "analyzer": {
        "hungarian_analyzer": {

Generated tokens

Use the following request to examine the tokens generated using the analyzer:

POST /hungarian-index/_analyze
{
  "field": "content",
  "text": "A diákok a magyar egyetemeken tanulnak. A számaik 123456."
}

{% include copy-curl.html %}

The response contains the generated tokens:

{
  "tokens": [
    {
      "token": "diák",
      "start_offset": 2,
      "end_offset": 8,
      "type": "<ALPHANUM>",
