For changes in the database, you can: - use the server side business object that also does the update of the BO in the database, and which currently does also the indexing in lucene - use the front-end (browser I presume if I see AJAX, which is nothing more than XmlHttp), but would not be my preference ... (use servlet or bean or ... instead) - use the database if it supports database triggers
But an update in the database will mean an delete and insert in Lucene, as far as I know. Remaining things (like push changed backend data to client) has nothing to do with Lucene.
