Integrating Zend Framework Lucene with your Cake Application
From the post:
This is a short tutorial that teaches you how to integrate Zend Framework’s Lucene implementation (100% PHP) to your application. It requires your server to have PHP5 installed, since ZF only runs on PHP5, and is likelly to be deprecated very soon.
Another search implementation guide.
Curious, (for my students), could I take the results of a search at one site and combine them with the results from another site? If that were your task, what questions would you ask? Is using the same search engine enough? If not, what more would you need to know? Is there anything you would like to do as part of the combining process? Assume that you have free access to any needed data.
