# Unified search across DataHub entity types

> Find documents + tables relevant to a query in one round-trip.

NexusOne tags each result with a ``type`` field so the caller can dispatch to
the right downstream endpoint. Use ``GET /documents/content`` for documents
and ``GET /metastore/...`` for tables.
