ali koyuncu commented on LUCENENET-534:
---------------------------------------

1- Yes I am using a WinForm.
2- You want to see minimum amount of code. So I removed some code. btnStartService_Click isn't
called in fact.
3- I have created index folder daily. İf fiAktifYes that is folder of today is not exist
, create a new index Folder. I changed fiAktifYes to True and False. But I have gotten same
bug both of True and False.
4- Yes compound files are slower than the normal format. But if the normal format is used
, i have gotten memory exception. I had researched reason of this exception but i am not remember
it now.

> 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
