List archive

[David Squance]

How long is the time lag before messages are searchable in the archive? 
  I know there has been a few postings re scrolling flds, and I've 
dumped the one I want to go back to.  I though by entering (in quotes) 
a phrase from a reply to one of the messages, I could work back through 
the thread and find the one I want, but it comes up with nothing (or 
old messages, if the phrase isn't unique to a particular message.)

Thanks,
Dave
