Feedly. How to get into the search?

Question

RSS

Good day!
There is: a site with an rss feed, you need to make it so that it is highlighted in the search for fidley and displayed in the directory there ... I would be very grateful if someone could tell me how fidley collects feeds for this directory?
PS link rel="alternate" for the rss feed is written in the head, so you can subscribe to the feed by entering the site URL, but there are no mentions in the catalog and search...
