How to set default index analyzer

[johnsonjackc]

Hello!

I'm trying to set a default analyzer for all indices and am running into some difficulties. I was trying via OPENSEARCH_DSL_INDEX_SETTINGS but maybe I'm doing it wrong? Any suggestions or tips would be greatly appreciated!

Here is how I have the settings:

OPENSEARCH_DSL_INDEX_SETTINGS = {
    'number_of_shards': 1,
    'number_of_replicas': 0,
    'max_ngram_diff': 3,
    'analysis': {
        'analyzer': {
            'default': {
                'filter': [
                    'lowercase'
                ],
                'type': 'custom',
                'tokenizer': 'partial_tokenizer'
            }
        },
        'tokenizer': {
            'partial_tokenizer': {
                'token_chars': [
                    'letter',
                    'digit',
                    'punctuation',
                    'symbol',
                    'whitespace'
                ],
                'min_gram': '2',
                'type': 'nGram',
                'max_gram': '5'
            }
        }
    }

You did it the right way, it does work on my end using your exact settings on the test project:

{
  "country": {
    "aliases": {},
    "mappings": {
      "properties": {
        "area": {
          "type": "long"

      }
    }
  }
}

What are your OpenSearch version, python version and django-opensearch-dsl version ?

So I ended up deleting the opensearch image and redownloading it and, not sure why, but now I'm seeing the analyzer info in the _settings query. Thank you for confirming I was setting it correctly!
