Searchable archives question

[d houlton x0710]

Who controls the archives for the list?  Would it be possible to change
the context (body) search to be a regexp instead of or-ing search
words together.  

It's next to useless for finding something if I have to wade through
700 messages because I can't narrow it down somewhat.

The Subject line search does use the regexp search which is why I ask.

thanks
