Simon, Below is the list of all Lucene packages that I import in my code. Any of these are not thread safe?

IndexWriter & IndexReader (IndexSearcher) can be shared between threads. Any other particular class you are in doubt with? simon On Mon, Apr 30, 2012 at 8:25 PM, Ilya Zavorin <izavo...@caci.com> wrote: > Hi All, > > I am looking for a definitive source on which Lucene core components involved > in indexing and search are thread safe.
