For my applications I have not need to access Lucene inside a transaction. WebDAV does not know about transactions, which span more than one HTTP request anyway. So it would be fine, when the data are indexed immediately after the slide transaction is committed. Just take care, that Lucene never sees data, which are not committed. If the WebDAV request should return, before the data are indexed depends on the application. Performance <=> Integrity. There is already the problem, that WebDAV requests sometime need a lot of time and the client may timeout despite the server running fine.
