List registry registrations matching a business name or filing number.
You must provide one of name or filing_number.

With an iso2_country_code, a search will be performed directly at the registry for that jurisdiction.
Without an iso2_country_code, a global search will be performed across all jurisdictions.

Pass a result's filing_number (with the country) to
POST /international/searches to run a lite or enhanced search for
exactly that company, skipping name/address matching.
