基于嵌套数组查询弹性搜索聚合

Question

I do have the documents like below in my index

{
      "bookName" : "coolbook",
      "timeStamp" : "2018-11-19T12:52:17.000Z",
      "referenceId" : "auth_test_01_01_000004",
      "peoplestatus" : [
        {
          "personId" : "p1",
          "status" : "like"
        },
        {
          "personId" : "p2",
          "status" : "dislike"
        },{
          "personId" : "p3",
          "status" : "netrual"
        }
      ]
    }

Now I want to query the aggregations of book count for person p1,p2 like below the counts of books

1. p1-liked but p2-disliked
2. p1,p2 both liked
3. p2-disliked but p1-liked
4. p1,b2 both disliked

Thanks for your help

Answer 1

Since you require buckets with different filter for each bucket, filters aggregation is best fit for this. As per your comment there will be two person ids to be compared following is the query for your following two combinations:

• P1 liked but P2 disliked
• P1 and P2 both liked

    {
      "query": {
        "match_all": {}
      },
      "aggs": {
        "books": {
          "filters": {
            "filters": {
              "P1L_P2DL": {
                "bool": {
                  "must": [
                    {
                      "nested": {
                        "path": "peoplestatus",
                        "query": {
                          "bool": {
                            "must": [
                              {
                                "bool": {
                                  "must": [
                                    {

                                      }
                                    },
                                    {
