[Drake] AC-4 filter capacitors -- searching the archives

[Steve]

I recall having seen some discussion of AC-4 filter capacitors on this 
list in years past. Now I need to replace the capacitors in my power 
supply but don't remember when the postings were made.

Is there a way to search the entire archive with a single search? I see 
the month-by-month archives at http://mailman.qth.net/pipermail/drake/ , 
but I'm hoping there is a way to search all of the posting at once 
rather than being constrained to a month at a time.

Advice?

Thanks.
