{
    "size": 20, 
    "query": {
        "bool": {
            "filter": [
                {

Check the release_issue value in returned documents. It responds with

      {
        "_index": "opensearch_release_metrics",
        "_id": "d76000bb-41cb-31ff-99da-d5b6c6ffc83b",
        "_score": null,
        "_source": {

          "release_notes": false,
          "version_increment": false,

      },

Everything apart from release_issue seems okay.
