How to remove low correlation results?

Elastic Stack Elasticsearch
1

I want to be able to filter my search results for less relevant results. So I use the min_score for filtering.

like this:

GET xxx/_search
{
  "min_score": 2.8,
  "query": {
    "match": {
      "xxx": "xxxx"
    }
  }
}

But the max_score is different for different search keyword, which leads to the fact that sometimes I need to filter results with a score less than 20 and sometimes I need to filter results with a score less than 10.

And this threshold I have no way to determine, anyone have any ideas?

For example, I searched for the term Maciachini Apartments R&R and the results returned with a score greater than 20 met my needs (return max_score is 40+) . But when I searched for the term R R, the words with a score greater than 10 were the ones I needed (return max_score is 10+) . So how do I determine this threshold?

Can there be any way to return es to a uniform score standard? Or is there any way I can filter the data for 80% of the maximum score?

Like this

GET xxx/_search
{
  "min_score": max_score*0.8,
  "query": {
    "match": {
      "xxx": "xxxx"
    }
  }
}
