Search Engine for Mhonarc: MHonArc-Search

Hi all,
I have written a small search engine for Mhonarc-Archives. Namazu is 
nice, but have some scalability-problems (in my case (approx. 200.000 
Postings in the archive)).
MHonArc-Search should provide a *good* Search-Engine for 
MHonArc-Mailarchives. It is not designed as an all-purpose Search-Engine 
like Htdig or Namazu. It is written in Perl and needs a Mysql-Database.
You can find my Sourcecode and a small ¨Readme" (Requirements, some 
installation-instructions, etc.) at 
http://oeh.tu-graz.ac.at/~dauti/mhonarc-search/
If you find it useful, please give some feedback and help to improve 
MHonarc-Search.
Bye,

Wolfgang Dautermann
