Hello,
I am currently working on a server app that will require the ability to make index additions/deletions at any time. I want to cache/reuse index searchers and readers. I know that once an index has changed only newly opened readers will see the changes. Creating a new reader to see the changes and caching it will be no problem. My problem is that since this is a multithreaded app other threads may be using the old readers making it difficult to know when to close them. I assume that a reader must be closed to free the associated resources. I was thinking about using some kind of reference counted reader that would keep track of its references and only truly close when there were no references. Am I making this too difficult? Is there a better way? I assume others have had to do this using Lucene, do you have any recommendations? Regards, Michael
