Wrong score value

Elastic Stack Elasticsearch
1

i tested below... but score value is not calculated correctly.
query with range filter is correct.(26)
but query with bool query is not correct. (26.023848)
but range filter is replaced by range query from ES 2.x.
how should i do?

Query with bool query:
{
  "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "query": {
              "function_score": {
                "query": {
                  "terms": {
                    "Log_Thing": [
                      "a",
                      "b"
                    ]
                  }
                },
                "functions": [
                  {
                    "script_score": {
                      "script": "doc['Log_Thing_Count'].value"
                    }
                  }
                ],
                "boost_mode": "replace"
              }
            },

i found that bool query handles score value to show how many conditions are mattched in bool query.
So, score value is increased due to bool query.
To avoid this situation, bool.filter can be used. bool.filter is not effected to score value.
This is explained in below linked site.
