Hi, I have bought the Lucene In Action Book for more than a year now, and was using Lucene 1.x during that time. Now, I have a new project with Lucene and Lucene is now 2.0. Many APIs seems to have changed.
I would like to ask the experts here, what are the important or substantial changes from Lucene 1.x to 2.0? Which part of the LIA book that is still usable and which part is not? Any particular things that a new Lucene 2.0user that only have used the 1.x version, should pay attention to? Thanks.
