For example:

const response = await client.indices.create({
  index: "my-index-000001",
  settings: {
    analysis: {
      analyzer: {
        my_analyzer: {
          tokenizer: "standard",
          filter: ["lowercase", "my_snow"],
        },
      },
      filter: {
        my_snow: {
          type: "snowball",
          language: "English",
        },
      },
    },
  },
});
console.log(response);
