Change match score mode from "sum of" to "max"

Elastic Stack Elasticsearch
1

Hello!
Sorry for my English ))
Tell me how I can change score mode from "sum of" to "max" on nGram field??
Due to the summation, the elasticsearch gives results that do not suit me. I need to get the maximum value, not the amount.
