Hi Michael,
Thank you for the question and the followup!
We have most certainly been releasing improvements that benefit the end user. In 7.x, here are some features App Search has released:
- Meta Engines – for cross-engine searching.
- Configurable Limits – so users can adjust some defaults that were set for SaaS.
- ILM support – users can set analytics and log retention, and manage it with Elastic Stack ILM tools.
- Search UI – a comprehensive set of front-end libraries
- Cloud SSO – for smoother login management.
- App Search on Elastic Cloud, so users have access to more hosting locations
- A self-managed version of App Search, in case you wanted to spin up your own
Hope that helps!
