Unfortunately, not that I'm aware of. The cached data you are seeing in Spotlight search is separate from the messages data on your phone, and you can't restore from one to the other.
Messages are, however, included in the iPhone backup (whether done with iTunes or iCloud). If these messages were on your phone when you last backed up, restoring to the entire backup should recover them.
