I think this is possible through ActiveState's archives here:

It appears to be a full-text search thing, but it's fairly good.

Hope this helps!

Definitely helps! Didn't know about this facility. Took only a few seconds to find the info I wanted, and I look forward to using it more. Many thank yous. Kirby
