Hallo!
I am a long-time SUSE user and I recently installed openSuSE Tumbleweed. During my system setup activities, I noticed that the search functionality in Myrlyn and Yast works differently. I have the feeling, the search function for available packages in Myrlyn misses some packages so that the results are incomplete. Those available packages can be found in Yast however.
For example, if I search for “freetype2”, Myrlyn does not show me the “freetype2-devel” package, but Yast does.
This happened to me also with SDL and CGAL packages.
I am using a fully updated Tumbleweed system and I am using the same search settings (search in name, keywords, summaries).
