You can do this using scripted fields: [https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)

However, it's highly recommended to use logstash for this, because scripted fields will be significantly slower. This is especially relevant when you are using them in filters.

Yes, in the script you can access the current document and use things like regexes to extract things from another string field.
