  • 'meta_value_num'.
  • The value of $meta_key.
  • The array keys of $meta_query.
  • 'none' to omit the ORDER BY clause.

  Default 'name'.
• orderstring
  Whether to order terms in ascending or descending order.
  Accepts 'ASC' (ascending) or 'DESC' (descending).

  Search criteria to match terms. Will be SQL-formatted with wildcards before and after.
• name__likestring
  Retrieve terms with criteria by which a term is LIKE $name__like.
• description__likestring
  Retrieve terms where the description is LIKE $description__like.
• pad_countsbool
  Whether to pad the quantity of a term's children in the quantity of each term's "count" object variable. Default false.
