Contribute to global index by submitting index actively

In the FAQ,

It mentions this line:

Our idea of ‘information wares’ and their exchange can also be applied to junior peers: they must contribute to the global index by submitting their index actively

For the active contribution of the index is this something a junior peer does automatically or is there some additional administrative task that needs to be run ?

From my understanding junior peers are not reachable for distributed queries. But they still can upload crawl data to World DHT. So you need to run your crawler to contribute. I’m not sure will “remote crawl” work for junior, but I guess it will not. So you need to create your own crawl task to contribute.

Thanks was initially going to try it out in junior mode. But ended up running a senior node anyway.
