Hi all.

I’ll be very lazy and ask around as opposed to dive deep 😛 is this

equivalent (now or evenctually) to the [Script score query | Elasticsearch Guide [7.3] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/query-dsl-script-score-query.html#vector-functions)

AND OR [Outlier detection | Machine Learning in the Elastic Stack [7.3] | Elastic](https://www.elastic.co/guide/en/elastic-stack-overview/7.3/dfa-outlier-detection.html) ?

would there be plans here for dataframes?

These topics (advances in information retrieval and data transformation processing for AI) are extremely important and i feel a good community could crystallize about keeping these topics in the open on Elasticsearch.

could it make sense to have a forum for ML and advanced Search features?

cheers

Hi @jccq good suggestion. We will setup a ML forum for discussions focused on related Open Distro components.
