First of all, to run real reindex process, you should always run it Async with the wait_for_completion=false URL parameter.

You will get a task ID and can monitor the progress with

GET /_tasks/<task_id>

You will have to relaunch it from scratch, but already existing docs will not be updated or recreated.
It's not perfect but it will be quicker than your initial load.
