Thank you for your response.  The user running the cgi and the user  
running at the shell (command line) are the same user.  I did a su -  
mailman to get the shell as the mailman user, which is the user  
running the cgi.

The index and the number of documents is small.  This is a small mail  
list used by basically two people -- the system owner and me, the  
person doing system manager work.  Here is what the search results  
say for the query strings that do work.  "This index contains 682  
documents and 23,287 keywords."

The issue is that apache is returning an error when certain query  
strings are given.  The error is "Premature end of script headers: / 
web/xxxxxx.com/mailman/cgi-bin/Admin-List/namazu.cgi"  which happens  
when a cgi does not output the necessary headers before it starts to  
output its own data.  It sounds to me like namazu is not getting the  
query string passed in correctly sometimes, or something like that.

Does namazu have a debug mode I can set for the cgi ? - nothing  
seemed obvious when reading the docs and install guide.  Something  
that will have the cgi output what it is doing, what it got as a  
query string, and what it is sending back to apache -- put into a  
debug log?
