I want build IR system in Java and I found Lucene, but some questions remained unanswered for me after searching complete website. I have couple of questions regarding Lucene, 1. What is the search algorithm(s)[VSM, ..] used or available in the Lucene? 2. How term weight is calculated in Lucene, how many types of term weight calculating formulas are implemented and what are they? Regards Madhu
Re: IndexWriter and IndexReader open at the same time
If you have the Lucene book, look at Chapter 2 (page 59 under section 2.9 (Concurrency, thread-safety, and locking issues) in chapter 2 (Indexing)): http://www.lucenebook.com/search?query=concurrency+rules Also, look at Lucene's Bugzilla, where you'll find a contribution that helps with concurrent IndexReader/IndexWriter usage.
