 To do so you need to set `skip_index_creation_on_import` parameter to `false` in your `config/chewy.yml`
 
+### Skip record fields during import
+
+You can use `ignore_blank: true` to skip fields that return `true` for the `.blank?` method:
+
+```ruby
+define_type Country do
+  field :id
+  field :cities, ignore_blank: true do
