Swish-e

From: Rich Thomas <thomasr(at)not-real.buffalo.edu> Date: Tue Jan 22 2002 - 13:37:22 GMT

I've tried using the sample cgi script that's provided in the Quick Start
documentation and keep getting an error

Bad keyword: `'. Please don't use commas or non-alphanumeric characters.

This comes up before I'm able to enter any search criteria.  I'm running the
latest swish dev on a Solaris 8 sparc machine.  Where is the script picking
up the input that it says is bad?  I'll attach the search.cgi script here.

Any help will be greatly appreciated!!!!  as always
