It looks like the Curse search index is not updating with new AddOns.

For example, search for Sorren's Timer, the auto-suggest fills in "Sorren's Timer 3" but searching for it finds nothing (and searching for just "sorren" doesn't find it either, only older versions of the AddOn).

 But if you do a google search for "Sorren's Timer 3" the first result is a direct link to the curse page for the AddOn that the Curse search couldn't find!
