  //
  // Histogram Facets:
  //
  // * admin1: Admin1 is a global placeholder for referring to state, province,
  // or the particular term a country uses to define the geographic structure
  // below the country level. Examples include states codes such as "CA", "IL",
  // "NY", and provinces, such as "BC".
  // * locality: Locality is a global placeholder for referring to city, town,
  // or the particular term a country uses to define the geographic structure
  // below the admin1 level. Examples include city names such as
  // "Mountain View" and "New York".
  // * extended_locality: Extended locality is concatenated version of admin1
  // and locality with comma separator. For example, "Mountain View, CA" and
  // "New York, NY".
  // * postal_code: Postal code of profile which follows locale code.
  // * country: Country code (ISO-3166-1 alpha-2 code) of profile, such as US,
  //  JP, GB.
  // * job_title: Normalized job titles specified in EmploymentHistory.
  // * company_name: Normalized company name of profiles to match on.
  // * institution: The school name. For example, "MIT",
  // "University of California, Berkeley"
  // * degree: Highest education degree in ISCED code. Each value in degree
  // covers a specific level of education, without any expansion to upper nor
  // lower levels of education degree.
  // * experience_in_months: experience in months. 0 means 0 month to 1 month
  // (exclusive).
  // * application_date: The application date specifies application start dates.
  // See [ApplicationDateFilter][google.cloud.talent.v4beta1.ApplicationDateFilter] for more details.
  // * application_outcome_notes: The application outcome reason specifies the
  // reasons behind the outcome of the job application.
  // See [ApplicationOutcomeNotesFilter][google.cloud.talent.v4beta1.ApplicationOutcomeNotesFilter] for more details.
  // * application_job_title: The application job title specifies the job
  // applied for in the application.
  // See [ApplicationJobFilter][google.cloud.talent.v4beta1.ApplicationJobFilter] for more details.
  // * hirable_status: Hirable status specifies the profile's hirable status.
  // * string_custom_attribute: String custom attributes. Values can be accessed
  // via square bracket notation like string_custom_attribute["key1"].
  // * numeric_custom_attribute: Numeric custom attributes. Values can be
  // accessed via square bracket notation like numeric_custom_attribute["key1"].
  //
  // Example expressions:
