Lucene's transactional, so that Lucene index is not real-time, if you want Lucene real-time, you must add a new document after IndexWriter need commit, in the search Indexreader need to reopen, However, when the index is on the hard disk, especially when the index is very large, the commit operation of IndexWriter and the open operation of Indexreader are very slow, and the need of real-time is not reached at all.In fact, the general application, if you can al

the same as general searches. Lucene. Net simultaneously searches for Multiple indexes When creating an index, you can create multiple indexes according to the category, and search for all indexes at the same time.
