While openSUSE is a great Linux distribution, I can't say the same for the mailing list's search function. For many weeks now, the only result that came back from the search is:
Sorry, the search is disabled! Come back later
Someone in the mailing list suggested that a workaround is to use Google's site specific search function. In the search box, prefix the search terms with the term:
For example, if I want to search for "usb boot support", I will type the following in the search box.
site:lists.opensuse.org usb boot support
Granted, it's not perfect, but it's a temporary workaround. shrug
