Description

I process new data list in memory-directory. After that I commit memory-directory to disk directrory. After I commit global index writer,I see the files isn't combined.So when I reopen the service,indexwriter deletes all files in global index folder. I traced codes ,
"deleter = new IndexFileDeleter(directory, deletionPolicy == null?new KeepOnlyLastCommitDeletionPolicy():deletionPolicy, segmentInfos, infoStream, docWriter, synced);" in IndexWriter Init method,it deletes all file here.

I asked it on stackoverlow. http://stackoverflow.com/questions/20973121/lucene-net-indexwriter-bug?noredirect=1#comment31536841_20973121
