Describe the feature you want

PeerTube is streaming videos peer-to-peer using WebRTC.

There now is a search engine: https://sepiasearch.org/

and one may install their own scraper, index and serve a search portal too, using the code https://framagit.org/framasoft/peertube/search-index

What would be interesting would be that Freetube sends the searched request to a PeerTube search API and displays the results among the results.

You may mutualize with the FreeTube team to implement this once for both projects.
