Comment 1 for bug 626435

The top three show in the same page are sorted by the karma of the source package's creator. This was designed like this specifically to a) not slow the page rendering down, b) not overwhelm the reader, and c) present the most useful results.

The "search for other" link does search on package names - if I click the link on the vlc page you suggested it reports 102 PPAs that contain vlc, including the 6 examples you've posted.

I'm not sure what else you mean? If I missed something can you let me know.

Thanks.
