That ticket is an optimisation. If your IDs are sequential, you can sort on them. Or you can add a timestamp field with a default of NOW, and sort on that. q=topic:x1&rows=20&sort=id desc Or q=topic:x1&rows=20&sort=timestamp desc Will get you what you ask for. The above ticket might just make it a little faster. Upayavira
