You shouldn't close your IndexReader/IndexSearcher unless all searches are done using them, otherwise you'll hit exceptions. Also, if you don't separately use the IndexReader, you can just open/close the IndexSearcher. However, it's better to use IndexReader's reopen method, which only opens the new segments created since the last time the reader was opened. > How does one get the early edition of the lucene book?

Chapter 11 in the book has a class called SearcherManager, that handles the details of reopen/closing the IndexReader while queries are still in flight, that might be useful here.
