 This allows you to backfill records while still querying the unencrypted field.
 
 ```ruby
-User.unscoped.where(email_bidx: nil).find_each do |user|
-  user.compute_migrated_email_bidx
-  user.save(validate: false)
-end
+BlindIndex.backfill(User)

 This will keep the new column synced going forward. Next, backfill the data:
 
 ```ruby
-User.unscoped.where(email_bidx_v2: nil).find_each do |user|
-  user.compute_rotated_email_bidx
-  user.save(validate: false)
-end
+BlindIndex.backfill(User, columns: [:email_bidx_v2])
