for rebuilding, no. But once you modify a record, without the :key option the old ferret document won't get removed when the record is re-indexed, so you'll end up with documents belonging to different versions of your record in your index. that's because ferret does not support updates of existing documents in the index, so updates are done by 'add new doc, remove old doc'. the :key option tells ferret how to find the old doc. However, I could have look into disabling the :key option for index rebuilds. A patch would be very welcome, too :-) cheers, Jens -- webit!
