Short query causes [too_many_clauses] too_many_clauses: maxClauseCount is set to 1024 why?

Question

How does a minimalistic query like below :-

{
  "sort": [
    {
      "updated_at": {
        "order": "desc"
      }
    }
  ],
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "merchant_id": "91"
          }
        },
        {
          "match": {
            "name": "ok"
          }
        },
        {
          "match": {
            "categories.keyword": "kitchenware"
          }
        },
        {
          "match": {
            "status": 1
          }
        }
      ]
    }
  }
}

Cause a error [too_many_clauses] too_many_clauses: maxClauseCount is set to 1024 ? is it even possible that q tiny query like this can cause a maxClauseCount error ?

Secondly , is there a way i can make out how many query's i'am asking elastic search to run , every time i run a search ?

Note :- Also i'am aware that this problem can be solved just by increasing the max_clause_count in the elasticsearch.yml file as show in this answer HERE
