Searches employers in the caller's company. Returns a page of employers
matching the supplied filters. Use the employer metadata endpoint
(/v1/employers/metadata/search) to discover available field IDs and
supported filter operators. There is no single-employer endpoint — read one
employer by filtering on /employer/id.

Before using this endpoint

• Discover readable field IDs (including custom fields) via the
  employer metadata search endpoint.
  Out-of-the-box field IDs are also listed as keys on the Employer response
  schema for this search endpoint.
• There is no single-employer endpoint — filter on /employer/id with
  operator equals to read one employer.
• Filterable field IDs: /employer/id, /employer/legalName,
  /employer/country, /employer/employerStatus,
  /employer/supportsRemoteWorkers. Any other fieldId in filters returns
  400 Bad Request.

Pagination — cursor-based. The first page is requested without cursor;
subsequent pages pass next_cursor from the previous response.
next_cursor is null on the last page. Search does not support sorting —
order results client-side.

Testing notes

• Use the testing widget's Try It! option to test this endpoint.
• Open Examples and select Request Example to populate the request
  body. The default example returns all employers with a core field set.
• IDs must be sent as JSON strings even when they look numeric, so that
  large values are not truncated by JSON number precision in clients.
