Hi, In general, the speed of the Lucene search depends on several aspects, one of those is of course the underlying hardware its IO performance. To improve search performance, one way is to use SSDs or increase the available file system cache of your operating system. Full text search engines are fast, because they only return the best-ranking results first (by using priority queues). Further increasing the result window size will slow down searches. So try to improve the relevancy by using better or more specific queries and apply filters instead of increasing the result set size. To do this we, need more information about the type of documents or queries you are using.
