Hello, I trying during log ingestion calculate the percentage of similarity between two fields. For example, A=foobar B=barfoor

I have read about this here: [similarity | Elasticsearch Guide [8.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/similarity.html)

But I dont knwo how apply it, maybe with a script processor in ingest-pipeline.

Thanks  
Diego
