CocoaBuilder was down for a while due to a server crash. I just discovered it's back up, with some very nice design improvements. Here are the changes I noticed:

• Clicking a message header toggles between just displaying the message header and displaying the entire message text inline.
• Long quoted passages are replaced by a "show quoted text" link that expands to show the quoted text. This, plus the inlining of message text, makes it much nicer to read message threads. The site is much more responsive and it minimizes redundant text.
• It remembers whether you prefer sorting by date or relevance.
• You can search for quoted phrases, as in underscore "instance variable".
• It does stemming, so searching for "instance variable" also finds the plural "instance variables", and searching for write also finds "writing".
• Now that you can use quoted phrases and specify sort order in the main UI, the "advanced" search button (or whatever it was called) has been removed.

Congratulations to Bertrand Mansion for getting the site back up, and huge, huge thanks for this invaluable resource.

UPDATE: In my excitement I didn't notice that it isn't live yet with recent posts, and there's still a few months of recent archives that haven't been brought back online yet. But there's still lots of searchable material, and if nothing else you can try out the new UI and send feedback if you have suggestions.
