Thanks for the answer. However those classes and methods are abstract. Should I write my own implementation? Since Lucene is able to do indexing and searching, I think there should be already implementation of these things.
Sorry, if Mike's answer also includes this obviously. But I couldn't get it, I need some further explanation.
