Subject Re: Search while indexing

I' found the problem

It was simply a question of Lock Directory.

The default one is System.IO.Path.GetTempPath(), the temp dir for the 
current user. if application are running as different users (quite often 
with web applications), the lock directory has to be specified in 
configuration file.

That FSDirectory.LOCK_DIR should maybe be safer by default, maybe a sub 
directory of  Environment.SpecialFolder.CommonApplicationData ?
