need to update search index after bundle is submitted

[Greg Couch]

This could either be done via a daily cron job, or it could be done when a bundle is submitted. The problem with the latter is that we don't want to slow down the submission process, so the update should be done asynchronously. But there could be another submission (or more) while the index is being rebuilt, so there would need to be a way to tell that another update is needed.

Perhaps a hybrid solution where submitting a bundle would create a file to signal that the index needs updating and a cronjob would update the index if it saw that file.

Fixed with periodic script to update the index daily.
