Refresh Interval Value for Read-only index

I'm wondering if not re-setting back to 30s or 60s will make any difference since this index isn't going to get any data post re-indexing.

Yes in theory you need to at least refresh it once when your done, unless something else did it for you. Thats why @dadoonet says you can leave it disabled but need to refresh it manually after.
