<strong>How to verify:</strong> Every number on this page was generated live by the server responding to your browser request.
|
||||
Hit refresh — the queries run again. These are not cached or pre-computed. The SQL tests execute on ${totalRows.toLocaleString()} real rows.
|
||||
The hybrid search finds real workers with real names, skills, and certifications — every result marked <code>sql_verified: true</code>.
