I am looking for a global the will take a series of keywords - that have been assigned to a link - and link them to a search of the database. I'm already aware of how to insert a column name to a search, eg.:

<a href="<%config.db_cgi_url%>/search.cgi?Keywords=<%Keywords%>"><%Keywords%></a>

This would work fine if the link only had one keyword, however each link is assigned anywhere from 5 - 20 keywords. They are seperated by a "," in the database.

Has anyone heard of a global that can accomplish this?

I am basically trying to create a tagging function for each of the links in the database. The links in the directory have all be assigned keywords, and I want the user to be able to click on a keywords (displayed on the links detailed page) and have all the links in the database that have the same keyword associated with it be pulled up on the search page. I am doing something similar with the [more] function here (for year published, author, etc:

It will essentially be a really simple tagging feature - similar to what you see on many weblogs and services like del.icio.us, etc.
