[elephant-devel] full text search solution?

[Glenn Tarcea]

Have you looked at Montezuma? http://projects.heavymeta.org/montezuma/

It's a port of Ferret (which is port of Lucene) to Lisp. It's also on  
the list for the google summer of code to add some additional  
functionality to it.

BTW: If its alright I'm going to update the docs to add a section on  
having two versions of Elephant installed and using ASDF to manage them.
