Like the title says. I was using the regular search operations in benchmark, but was considering switching to msearch. I know it is not in the documentation spec, but is there a way to emulate it, or is it on the way in a newer ESRally version?

Hello!

We have an issue in our backlog to address this in esrally core ([elastic/rally#300](https://github.com/elastic/rally/issues/300)) but in the meantime it is possible to do this, either with a `raw-request` or with a custom runner.

An example `raw-request` can be found in the issue [here](https://github.com/elastic/rally/issues/300#issuecomment-591834696)  
An example custom runner using the ES client's msearch functionality is implemented in the public eventdata track [here](https://github.com/elastic/rally-eventdata-track/blob/6/eventdata/runners/kibana_runner.py#L45)

More information on custom runners: [Rally Docs](https://esrally.readthedocs.io/en/stable/adding_tracks.html?highlight=custom%20runner#custom-runners)

Hope that helps!  
Rick B
