Description Massimiliano L 2025-09-28 09:19:23 UTC

SUMMARY
Certain packages in Discover cannot be found by their title. For example, if I search for "0ad" Discover shows the app with title "0 A.D." but searching for "0 A.D." will return an empty result.

STEPS TO REPRODUCE
1. Use Discover with Flathub configured as a package source
2. Search for "0 A.D." (without quotes)

OBSERVED RESULT
The "0 A.D." app does not appear.

EXPECTED RESULT
The "0 A.D." app does appear. However the app appears when searching for "0ad".

This works for me on KDE Linux. Both Discover and `appstreamcli` find it:

appstreamcli search 0ad
Identifier: 0ad.desktop [desktop-application]
Name: 0 A.D.
Summary: A real-time strategy game of ancient warfare
Package: 0ad
Icon: 0ad_0ad.png
---
Identifier: com.play0ad.zeroad [desktop-application]
Name: 0 A.D.
Summary: Real-time strategy game
Bundle: flatpak:app/com.play0ad.zeroad/x86_64/stable
Homepage: https://play0ad.com/
Icon: com.play0ad.zeroad.png

I'm guessing that for both of you, `appstreamcli search 0ad` doesn't find it, right?

It looks like the 0 A.D. issue was a bug in AppStream itself: https://github.com/ximion/appstream/issues/702. I have version 1.1.0, and I bet you two have an older version.

Indeed, 1.1.0 just landed on Fedora and fixed the issue for me.

The new title is wrong though: I could always find the software with the "0ad" string, but I could not with the "0 A.D." string.
