## When to prefer this

Choose this endpoint when you need exact, literal vocabulary matching against a manufacturing quality publication index — particularly for citation-grade source retrieval or publication planning where fuzzy or semantic search would introduce false positives. Prefer it over semantic search endpoints when the user needs to verify the precise presence of a specific term in indexed sources.
