The MySQL hack found on 
http://www.extropia.com/hacks/webstore
 
needs to be revised.  I have attached the two files needed 
in .zip format as linked on the following page.

I have attached the wsmysql.zip file so you can easily 
rewrite over the old version at:

Please note that in this version:
 
In this version of web_store_mysql_db_lib.pl, the mysql_build_criteria
subroutine now includes individual options for exact matching and case
sensitivity for each "string" type criteria, exact phrase matching and
wildcard matching.
