Hi, I think the Lucene Directory is in good shape; I'm not aware of any good reason to not include it in CR2; still some improvements could be done on locking, but I'll keep that to another thread. I've prepared a little demo-like application to run in a terminal, you can launch it several times and then add/query a simple string on the different processes and verify they are sharing the index. This is not in SVN and would need a couple of hours to frame it in some packaging; would you like me to contribute it somewhere? as a subproject of lucene-directory or demos/lucene ? The "demos/directory" is clashing a bit on names, any better option? cheers, Sanne
