The search is horrible. I searched for my podcast by keyword and by name, as well as some other podcasts I listen to and none came up even related to any of the shows I was looking for.
"Docker" - 1 result, about a personal brand podcast
From a quick inspect, looks to be just a SPA sending all search through Algolia, as opposed to a search geared toward podcasts specifically. (my understanding is that you can customize the indexes setup in Algolia, but with podcasts, I assume the naive approach is to just throw all the RSS text at it and assume that's adequate)
