Yes Lucene has build-in concurrency management. You can freely search and update the same index in different threads. One point here is that you have to use the same instance of the IndexWriter in updating threads. Trying to open the same index twice will throw exception. It is also recommended to share a single IndexSearcher across threads for better performance.

Does Lucene.Net have built into it logic for managing concurrency, multiple threads? If a request comes to my website that triggers a thread to update the index, and another request comes on another thread that also triggers a request to update, or even read, the index, does Lucene handle the management of concurrency, or do I need to?
