Incorrectly convert nested query

PUT index
{
  "mappings": {
    "my_case": {
      "properties": {
        "events": {
          "type": "nested" 
        }
      }
    }
  }
}

I made mapping structure like this. every row has more than two events data and would like to find one of events that matches poid and oid.

select name from my_case where (events.poid='A' and events.oid='B');

This is how I tried to query through sql4es, but It seems not results as I expected.

from sql4es
{
  "size": 200,
  "timeout": 10000,
  "post_filter": {
    "bool": {
      "must": [
        {
          "nested": {
            "query": {
              "term": {
                "events.poid": "A"
              }
            },
            "path": "events"
          }
        },
        {
          "nested": {
            "query": {
              "term": {
                "events.oid": "B"
              }
            },
            "path": "events"
          }
        }
      ]
    }
  }
}

It found every events that has poid is ‘A’ OR oid is ‘B’. How should I made query to find matching both condition?

This is what I want to make through sql4es

   .....
    "query": {
        "nested": {
           "path": "events",
           "filter": {
               "bool" : {
                    "must" : [
                        {"term" : { "events.poid" : "A"}},
                        {"term" : { "events.oid" : "B"}}
                    ]
               }
           }
        }

Thanks for your thorough explanation of the problem! I understand the issue and my guess right now is that it is a bug in the driver which I will have to verify. The last example in your post is exactly what it should be and ill look into it (might be a bit tricky to get it done though so will take some time)
