At risk of pulling this way too far off topic, may I ask how many
documents (mail messages) you were dealing with when things started to
fall apart with mnogo? We're looking at it for a new project that will
hopefully get bigger and bigger. We will be throwing groups of mailing
lists into their own mnogo config/tables... If we should save ourselves
the pain and look at something more homebrew, then we'll start
investigating "Tsearch".
Thanks,
Charles
