I agree this is disappointing.

As for the issue itself, it's hard to filter out. All of these applications list torrent in their description. See the listing below for details.

Maybe we could think of something to improve sorting.

As for how they actually show, it's coming from the repositories and we have to list everything. Maybe it's something to point out to Ubuntu and Debian.

Here's a related bug report in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/weboob/+bug/1782560

Same also in Debian https://lists.debian.org/debian-devel/2018/07/msg00263.html

Glad to see the Debian devs are taking a second look at these packages.  I'm thinking maybe having a popularity ranking system (like stars), similar to the old Ubuntu store and the Mint store, might help sort these apps to the bottom when typing in torrent.  I agree, it looks to be a difficult problem when the apps have "torrent" in their descriptions.

(In reply to wereturtle from comment #4)

See Bug 399502.

Beyond that, I don't really see what else we could do here. It's up to distros to filter out obscene and offensive names, or at least mark them accordingly.

Now that I think about it, another option could be to only show search results that have any ratings, or an overall rating that equals or exceeds a certain threshold (3 stars? 2 stars?), with a button at the bottom of the list that says "show more" that will load the full list.

(See Bug 399503)

Closing as it's a problem in Debian/Ubuntu and they're already fixing it.
There's other issues with searches that are being looked into.

Thanks for your patience!
