No hits field at all in search results

Elastic Stack Elasticsearch

I have products index, and when I run a query in Dev Tools like so I see results:

GET /products/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "merchant.id": "1"
          }
        }
      ]
    }
  }
}

Result:

{
  "took": 0,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": {
      "value": 1,
      "relation": "eq"
    },
    "max_score": 0.2876821,
    "hits": [
      {
        "_index": "products",
        "_id": "1",
        "_score": 0.2876821,
        "_source": {
          "id": 1,
          "status": "available",
          "category": {
            "id": 1,
            "name": {
              "en": "Pizza",
              "ru": "Пицца",
              "uz": "Pitsa"
            }
          }...

But when I run it with my nodejs app I see results with no hits field at all:

const result = await esClient.search({
      index: "products",
      type: '_doc',
      body: {
        query: {
          match_all: {
            "merchant.id": merchantId
          }
        }
      }
    });

and the results here is:

{
  "body": {
    "_index": "products",
    "_id": "_search",
    "_version": 3,
    "result": "updated",
    "_shards": {
      "total": 2,
      "successful": 1,
      "failed": 0
    },

Welcome!

You wrote match_all in the second query but match in the first.
But I'm not sure it's the problem here.

Elasticsearch seems to see your request not as a search request but a put document request.
I don't why as I don't see the full code but that might give you a clue.

Thanks for looking at this issue, I found a solution, on my local, I have been using es v7, but I got v8 on staging, sdk on nodejs was v7 too, so I migrated my local es to v8 and updated nodejs library to v8.
