Add redirects on Search

Trying to implement redirects on a Magento site using Algolia. I’ve read this documentation:https://www.algolia.com/doc/tutorials/search-ui/ux-patterns/how-to-add-redirects-on-search/

I already have Indices created, so can I just upload the JSON manually? Will this append it?
I’ve inherited this so I don’t want to affect anything that has preceded it.
