      summary: Search persons by name
      description: 'Searches for natural persons by name (first name, last name, or both).

        Returns a deduplicated list of matching persons with their `person_id` key

        and the number of companies they are linked to.


        Use the returned `person_id` with `GET /persons/{personId}/connections`

        to fetch full connection details.


        Identification is restricted to name-based queries (first name, last name, or both).

        Protected data, including PESEL and exact birth dates, is never exposed.

        To assist with identification, every result includes a `birth_year` (integer).


        **Result capping:** internally the search scans up to 2 000 matching link

        rows before aggregation. For very common names the response may include

        a `note` field indicating the result set was truncated; use a more specific

        query to narrow results.'
