Search multiple topics and deduplicate by question ID.
AI agents call search_multi to retrieve information from SearchCAIE MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters educational content (past-paper questions) across multiple topics. It performs deduplication but does not modify, delete, or execute anything. The operation is a pure data retrieval with no side effects, placing it firmly in the Read category with low severity.
