You cannot, you need to close the index. ---

If you had an alias you were querying through, you could keep two versions of the index. This would allow you to modify close the one the alias is not currently pointing to and you can then change the alias when the change is complete. This would allow you to change without downtime but would take up more space on disk. ---
