I am currently navigating Elasticsearch and Kibana version 8.7.1 and have encountered a challenge

**The Challenge: Aggregating Nested Fields**

My primary goal is to efficiently aggregate data residing within nested fields in my Elasticsearch index. While using Kibana's built-in filtering options, I've noticed discrepancies in the results, which has raised some questions about data accuracy.

**Questions That Pique My Curiosity:**

1. **Aggregating Nested Fields:** How can I accurately aggregate data from nested fields within Kibana 8.7.1? The standard filtering mechanisms don't seem to yield the precise numbers I require. I'm eager to learn more about the best practices and strategies for tackling this.

2. **Scripted Fields in Kibana 8.7.1:** Additionally, I am keen to explore the world of scripted fields within Kibana 8.7.1. I believe that harnessing scripted fields might be the key to obtaining the insights I seek. If anyone has insights into how to craft and leverage scripted fields effectively, I'd love to hear from you.

I welcome any tips, examples, or guidance you're willing to share.

To visualize them directly the only option available so far is Vega, as they are not supported in Visualizations: [Nested field support in Visualize · Issue #58175 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/58175)

> **Scripted Fields in Kibana 8.7.1**

While it works as a workaround to get access to a nested field content via scripted fields, it is worth mentioning that scripted field are a deprecated feature.  
There's some investigation for runtime field support as well (which are the successor of scripted fields) you can track here: [Nested field support · Issue #1084 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/1084#issuecomment-1116735966)
