Hi, I am looking for ways to improve the performance of lucene search in our app. Lucene performance is visibly slow when there are a lot of documents to be returned (performance almost seems directly proportional to the number of documents returned by Searcher). However, we show 20 results per page, so it seems to be a waste of time to get all, say, 60,000 documents when all I need are the nth 20 (i.e. if user requests 4th page of results, I just need documents 61 to 80). I've tried using the Searcher.search() method that returns TopFieldDocs. This method works much faster than the ordinary Searcher.search() that returns all the results. The trouble with this method is that I cant use it to get an arbitrary portion of the results, I can only get the top few docs.
Our index size is around 50 MB. Its optimized every one hour. I have tried a RAMDirectory, but even though using this improves performance by upto 2 times, its not good enough. Also our index gets modified by multiple processes so keeping the RAMDirectory up-to-date is a hassle.
