MUD-Dev is archived on the web at Kanga.Nu. The archives are
searchable. The problem, per se, is that often the simple searches
return too many hits. Search for "skill trees" and you get an
unmanagably large set of messages in return. It is useful to be
able to narrow the field of search by adding logic to the search
pattern, by being able to say what must be present, what must not,
what may be present etc.
The answer is the ability to do more complex, or "intelligent"
searches, which use logic (AND, OR, NOT etc) to phrase a search
pattern that (hopefully) matches only what you are interested in.
In essence this is the same thing as the '+' and '-' signs with
AltaVista, or the "must contain" and "must not contain" fields with

Dominic J. Eidson did a good job of the rest, providing examples and
such, so I'll leave that bit there.

Outside of the simple logic patterns that Dominic described, you can
also do more complicated expressions called "regular expressions", a
(massively useful) thing inherited from Unix. Regular expressions
are not trivial to describe usefully, but the following may help:
More simply (ha!), regular expressions allow one to define the exact
contents of a match, down to what letters and words may or must or
must not be present, in what order, and what may or may not lay
