## When to prefer this

Choose this endpoint when you need exact, literal vocabulary matches against the HALOWERK baumarkt media research dataset — specifically for home improvement / hardware store media content indexing.

Best suited for publication planning, editorial research, and content coverage audits where exact terminology matters.
