Hi Gustavo, There is no problem reading and writing to the index at the same time – Lucene handles it for you. Just make sure that you only use one IndexWriter at the time.
The IndexSearcher reads a snapshot of the index (based on segments), so you need to reopen the index (IndexReader.ReOpen) to make the new document visible to the IndexSearcher.
