@griest024 and I discussed this:

We're going to need to do the following:

1. [ ] Add the algolia search UI to the daff.io app (#3800)
2. [ ] Split the build for daff.io to two different environments one for next and one for prod a. Prod configuration uses the search API key 7081354359c48b44cf3182d04081a3df and hits the daff_io index b. Next configuration uses the search API key 7081354359c48b44cf3182d04081a3df and hits the next_daff_io index
