As I read the papper "[Optimizing Top-k Document Retrieval Strategies for

```

Block-Max Indexes]([http://engineering.nyu.edu/~suel/papers/bmm.pdf](http://engineering.nyu.edu/~suel/papers/bmm.pdf))", i see that each block of posting list stores one max score using to skip the block whose max score is less than then θ value，and max score value is based on term frequency and document length.  
My question is that can we use the score stored in payload as max score? I have a slow query as follows：

```auto
GET my_index/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "terms": {
            "tags": [
              "101",
              "102",
              "103",
              ...
            ]
          }
        }
      ]
    }
  }
}

```

Hundreds of terms in tags list , this is very slow , because es need to merge hundreds of posting list , my idea is to store a quality score in payload , and then use the quality score as max score of block, so this maybe can skip lots of block whose quality score not in Top-K hits  
Does this idea es support？

OR can block max wand algorithm use the value of [Index Sorting](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/index-modules-index-sorting.html#early-terminate) field as score?
