You can only reindex from remote in 5.0.

Yeah, only in 5.0+. Sorry about the misleading error message there. We are slowly making the parsing more strict but that stuff (it is a search request in there) hasn't been converted yet. So when you specify unsupported stuff it is just thrown on the floor.
