The Open Distro project is archived. Open Distro development has moved to OpenSearch. The Open Distro plugins will continue to work with legacy versions of Elasticsearch OSS, but we recommend upgrading to OpenSearch to take advantage of the latest features and improvements.

Refresh search analyzer

With ISM installed, you can refresh search analyzers in real time with the following API:

POST /_opendistro/_refresh_search_analyzers/<index or alias or wildcard>

For example, if you change the synonym list in your analyzer, the change takes effect without you needing to close and reopen the index.

To work, the token filter must have an updateable flag of true:

{
  "analyzer": {
    "my_synonyms": {
      "tokenizer": "whitespace",
      "filter": [
        "synonym"
      ]
    }
  },
  "filter": {
    "synonym": {
      "type": "synonym_graph",
      "synonyms_path": "synonyms.txt",
      "updateable": true
    }
  }
}
