I want to search with Lucene on an index. The index is changed frequently. So I need to do something to search and index at the same time. It's a web application on Tomcat. And I want to use RAMDeirectory to increase the searching speed. I don't know how to do it!
推荐答案
misc Lucene 包中的NRTManager 提供同时搜索和索引的能力.
NRTManager in the misc Lucene package provides the ability to search and index at the same time.
TrackingIndexWriter writer; // your writer
SearcherFactory factory = new SearcherFactory();
NRTManager mgr = new NRTManager(writer, factory);
