elasticsearchHow do I open an index in Elasticsearch?

To open an index in Elasticsearch, you can use the open API. This API takes the index name as a parameter and returns a boolean value indicating the success of the operation.

PUT /my_index

{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 0
  }
}

PUT /my_index/_open

{
  "acknowledged": true
}

The example code above creates an index named my_index with 3 shards and 0 replicas, and then opens the index. The output of the second PUT call should be {"acknowledged": true}, indicating that the index was opened successfully.

The open API can also accept other parameters, such as timeout and master_timeout. For more information on these and other parameters, please refer to the Elasticsearch documentation.
