Node Elasticsearch module search not returning results

I'm setting up a project with node (v 12.4.0) and elasticsearch (7.4.0) using the official module.

I'm attempting to search using

import { Client, RequestParams, ApiResponse } from '@elastic/elasticsearch'

const client = new Client({ node: 'http://localhost:9200' })
const params: RequestParams.Search = { index: 'doc', body: { query: { match: { title: "castle" } } } };
const response: ApiResponse = await client.search(params);

This gives a 200 response, but no results.

Attempting the same thing using Postman returns the 1 result.

POST http://localhost:9200/doc/_search
{
    "query": {
        "match": { "title": "castle" }
    }
}

I'm not having any luck figuring out why the search function is not working. I've also tested get, add, and delete, which all work.

To create the index, I used:

await client.indices.create({ index: "doc" });

To add a document, I use:

await client.index({
    index: 'doc',
    body: {
        title: "Castle Title",
        body: "This is text that is not the title."
    }
});

What am I doing wrong?

I've tested this and it works, the only thing is that elasticsearch is near real-time searchable. You need to wait 1 second before the document becomes searchable. Basically, if you are running a test or something, where you save the record just before searching you need to either:

  1. wait for 1 second before searching
  2. trigger a manual refresh https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-refresh.html
  3. wait for it to be refreshed when saving https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-refresh.html
