Hi, all, I am using Lucene.NET to index data. Meanwhile, more new data is frequently added to the index. However, if so, the retrieval performance becomes much lower when new data is being added and indexed because the indexing (writing) thread must synchronize the retrieving (reading) threads. I use .NET locks to manage the threads myself. Is it necessary? Or Lucene can handle the synchronize itself? I would like to know if it is possible for me to append one portion of Lucene indexes to another one. If so, it is easy to replicate Lucene indexes and the writing and reading do not affect each other. Or any other solutions in this case? Thanks so much! LB
