I discovered Yider some weeks ago, as a part of building a client website
why inventing the wheel again when there are nice open source code out there
to suit ones needs?

It is actually a brilliant search engine build in ASP, the only drawback is a lack of control panel, but the config files are pretty straight forward.

I've gone through the source and working on a controlpanel and transforming it into a mod for my own "framework", hopefully it will all be released in a couple of months
