Rebuilding indices should always be straightforward, and your data should be very accessible in some other (preliminary) form. We ran into so many issues, and had so many panics, because the index had become the only place some things existed. It's also way easier to tweak (read: optimize) your schema over time when you're in the habit of rebuilding the index.
