What diffirent about nested and bool composite query

[sslhj]

I have devloped a component that translate expression to esdel, now i have an exp like that
"((extras.key== ‘k1’ and extras.value==100 ) or (extras.key== “k2” and extras.value==”v2”))", in that, ”extras“ is a nested field
we have tow strategies to do that:

1. the whole is bool query,
   bool(or)
   -- nested bool(and)
   -- nested bool(and)
2. the whole is nested query
   nested
   • bool (or)
     -- bool (and)
     -- bool (and)

{
  "query": {
    "bool": {
      "should": [
        {
			"nested": {
			  "path": "extras",
			  "query": {
				"bool": {
				  "must": [
					{
					  "term": {
						"extras.key": "k1"
					  }
					},
					{
					  "term": {
						"extras.value": 100
					  }
					}
				  ]
				}
			  }
			}
		},
		{
			"nested": {
			  "path": "extras",
			  "query": {
				"bool": {
				  "must": [
					{
					  "term": {
						"extras.key": "k2"
					  }
					},
					{
					  "term": {
						"extras.value": "v2"
					  }
					}
				  ]
				}
			  }
			}
		}
      ]
    }
  }
}

                            "extras.value": 100
                          }
                        }
                      ]
                    }
                  },
                  {
                    "bool": {

                            "extras.key": "k2"
                          }
                        },
                        {
                          "term": {
                            "extras.value": "v2"
                          }
                        }
                      ]
                    }
                  }
                ]

Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.
