Sort types

For sort operations, given a field, GraphQL creates an enum of all fields (which accounts for up to three levels of nested fields) for a particular type, such as the following:

enum BlogFieldsEnum {
  id
  title
  date
  parent___id
  # and so forth
}

This field is then combined with another enum containing an order (ASC for ascending or DESC for descending) into a sort input type:

input BlogSortInput {
  fields: [BlogFieldsEnum]
  order: [SortOrderEnum] = [ASC]
}
