In the Feeds Manage Sources section, you were not able to find out the feeds that had a query string.
For example, these two links http://rocket.mydevenv.co/feed/ and http://rocket.mydevenv.co/feed/?post_type=property (belonging to one domain) were regarded as the same, and that limited the results.
In this improvement update, we have fixed that issue and now these two links with one domain are regarded as different RSS links.
Now you can operate multiple feeds, even if they just belong to one domain! This feature can be seen in Discovery too.
