Thanks Ian. >>The deprecation warning in the javadocs says "Please pass an ExecutorService >>to IndexSearcher, instead" so I'd do that. I may need to use IndexSearcher(Reader, ExecutorService). I have sharded my index. Say if i have 10 indexes then i will have 10 IndexSearchers. How to use this API. It takes one Reader and ExecutorService.
What about using IndexSearcher(ParallelReader)? >>Regarding optimization? I have sharded to multiple small indexes (in a single system). This helps to do faster indexing. I have updates every couple of minutes and the updates will go in latest shard. All shards will be optimized per day. If lucene performs well in searching multiple segment then i don't need to go for shards. I could very well use single index and don't optimize it. Whether it will impact search? Previous releases perform better in optimized indexes. What about 3.5.0?
