es查询报错circuit_breaking_exception","reason":"[parent] Data too large,异常

查询数据大概在两百万左右,语句如下:
{
        "_source": ["_id"],
            "query": {
              "bool":{
                "must": [
                  {
                     "match": {
                  "deleteStatus": "1"
                }
                  }
                  #if($sourceIp!='' && $sourceIp),
                   {
                  "terms": {
                        "sourceIp": #[sourceIp,serialJson=true]
                     }
                }
                #end
                #if($purposeIp!='' && $purposeIp),
                   {
                  "terms": {
                        "purposeIp": #[purposeIp,serialJson=true]
                     }
                }
                #end
                ]
              }
                
            },
             "size": 20000000,
            "track_total_hits": true
            }
报错如下：

解决思路:认为是请求时，内存不足，导致的请求熔断，之后采用GET _nodes/stats请求拿到返回数据进行查看
返回数据如下：
