Hi @r1ckC139

I believe the api explain can help you understand.

[Understanding the Explain API & Elasticsearch Scoring](https://opster.com/guides/elasticsearch/search-apis/elasticsearch-scoring-understanding-the-explain-api/#:~:text=Scoring%20Mechanisms%20in%20Elasticsearch,%2C%20and%20field%2Dlength%20normalization).
