I just implemented the PrefixQuery and FuzzyQuery in LuceneKit. In LuceneKitExample, you can search GNU* as prefix query, but because of the command line expansion, you might want to use GNU\* FuzzyQuery is not used in LuceneKitExample, but it passes all the tests.
I plan to make a release on GNUstep and probably Apache Lucene maillist next week. I think LuceneKit is ready to use. Bug reports are welcome. Have fun. Yen-Ju
