Scott Ganyo posted an IndexAccessControl class that can be used to manage searchers. After that we discussed it in private emails. I hope this logic can be part of Lucene some time. I've attached my last version of IndexAccessControl (iac). Use: // You first make an instance of IndexAccessControl. IAC is as many // instances as many directory (or index path) the application wants to use. IndexAccessControl iac = IndexAccessControl.getInstance(directory); // Request a searcher Searcher searcher = iac.getSearcher(); // use the searcher here // close it: iac won't close the searcher only returns it to a cache (or it can be called pool with size 1) searcher.close(); This code is as fast as you had only one IndexSearcher in your app (to be exact there is only one real searcher opened). IndexAccessControl has also methods for managing Writers and Readers. peter ps: to compile this code you must modify some classes of lucene: Searcher, Directory etc.
