The more often the term appears the lower is the relevance score. Field normalization factor (`fieldNorm`) | The length of the field. OpenSearch assigns a higher relevance score to a term appearing in a relatively short field. The `tf`, `idf`, and `fieldNorm` values are calculated and stored at index time when a document is added or updated. The values might have some (typically small) inaccuracies as it’s based on summing the samples returned from each shard.
