I looked only at your application's screenshots and based on that my guess is that you have a fairly high number of index fields, and if I recall correctly that can cause the above error. This was mentioned on one of the lists fairly recently, I believe. > Also, on a somewhat related note, how do I "shut down" Lucene > properly. > Eg, do I need to do anything with the IndexWriter and so on? This was mentioned on the list once, too. I suggested using a shutdown hook in Runtime package, but then somebody responded with a drawback of that approach. > Last, but not least, is there a way to turn of the file locking in > the latest rc as it's really getting in the way :-( Not that I know. If locking is getting in the way maybe you are not using Lucene properly. I haven't downloaded your application yet, so I haven't had the chance to peek at the source. > Finally, I just wanted to make sure: Lucene is fully multi-threaded > right? I can do search *and* write concurrently in different threads > at the same time on the same index? Yes, I believe so - I never encountered any problems with that. > BTW, should I post this kind of question to user or dev? I suggest -user until/unless we determine that there is something in Lucene that we can fix or improve. Otis __________________________________________________ Do You Yahoo!? Yahoo!
