I provide a basic indexing and retrieval code using the PyLucene 3.0 API.Lucene In Action (2nd Ed) covers Lucene 3.0, but the PyLucene code samples for have not been updated for the 3.0 API, only the Java ones. Unfortunately, there is currently little (no?) example PyLucene code in blogosphere. If you have links to more Lucene 3.0 tutorials and samples, please share them in the comments.
