Also, if this always happens, we may want to run this in the --init.

I don't think that's a good idea, it will destroy the search index every time we run it with --init

That's true. Although, the --init argument is receiving another meaning now. We should use it only for init.

Currently, as the workflow is right now, it's already broken. Always, the first time that you setup your development environment, you will have to use the troubleshooting section.

@stsewd @humitos we should add the search index creation to the --init, that should stop this issue from happening.
