I just heard of Lucy from lucene maillist. We have an objective-c port of Apache Lucene in Etoile project (www.etoile-project.org). It works for Cocoa on mac and GNUstep on Unix. It is basically a class-to-class port and pass most of the unit tests. Unfortunately, it suffers the same issue of most of other ports. So I am glad to hear Lucy and hope it will reduce the overhead of our objective-c port.
Have fun. Yen-Ju
