   * Describe options for available for use in the search-builder.

   * unique-name in the API matches the unique-name in the search-builder).

   * @param array $fieldOptions

   *   For boolean options, use value "yesno". For pseudoconstants/FKs, use the name of an API entity
   *   from which the metadata of the field may be queried. (Yes - that is a mouthful.)
