Internal search on this blog ain't workin'

I just tried an internal search and was dismayed to find... nothing. Using keywords from recent posts also returned nothing. Argh!! Not sure why this is the case as the settings were supposed to allow the blog to be ping'ed. The setting for 'notify weblogs.com' was 'yes', but 'add your blog to our listings' was set to 'no'. Not sure if the latter had anything to do with the problem. Will have to investigate further... I've set it to 'yes' and will check back in a couple of weeks at the latest...
