Maybe I should add that I am currently using Lucene 2.0. From other threads I get the impression that this might be solved in Lucene 2.1.

I am dealing with Index Directories of several GB. Opening and IndexSearcher is very expensive and can take several seconds. Therefore I am caching the IndexSearcher for re-use. Our indexes are frequently updated. Before I pass the IndexSearcher retrieved from the cache I use the IndexSearcher getIndexReader() method to get the IndexReader and to check if the IndexReader is current (via the isCurrent() method). The isCurrent method is documented as follows: /** * Check whether this IndexReader still works on a current version of the index. * If this is not the case you will need to re-open the IndexReader to * make sure you see the latest changes made to the index. * * @throws IOException */ Opening a new IndexReader is trivial. But then how do I set the IndexSearcher's reader to the new one without getting a new instance? Thanks in advance for any help.
