  "kind": "protocol",
  "body": "Extract the few concepts that determine relevance, then search each with its own synonyms. Combine synonyms within a concept with OR and combine the core concepts with AND where the search system supports it. Start broad enough to learn the field's terminology before adding extra constraints.",
  "limits": [
    "Over-decomposition can remove relevant records; keep only concepts essential to eligibility."
