Hi everyone,

I want to adjust the score according to the range of a particular field in function\_score.  
For example, I have the following query in mind.

```auto
{
   "query":{
      "function_score":{
         "query": { ....hogehoge }
      },
      "functions":[
         {
            "filter":{
               "range":{
                  "lastLogin":{
                     "lte":"2022-05-29T06:58:53.652Z"
                  }
               }
            },
            "weight":1
         },
         {
            "filter":{
               "range":{
                  "lastLogin":{
                     "gte":"2022-05-29T06:58:53.652Z",
                     "lte":"2022-05-30T06:58:53.652Z"
                  }
               }
            },
            "weight":2
         },
         {
            "filter":{
               "range":{
                  "lastLogin":{
                     "gte":"2022-05-30T06:58:53.652Z",
                     "lte":"2022-05-31T06:58:53.652Z"
                  }
               }
            },
            "weight":3
         },
         ..... and more
      ],
      "score_mode":"sum"
   }
}

```

However, I'm afraid this writing style is not performing well  
Is there any efficient way to write it?  
The version of ES used is 6.8.12

Thank you.
