You are building an LLM-powered assistant that answers questions about a hosted search platform. The assistant should explain what the platform's search API does, how developers use it, and where it fits relative to indexing, ranking, and analytics. You want the answer to be accurate and grounded in product documentation, not a vague marketing summary.
How would you explain the core functionalities of a search API in the context of an LLM-powered product experience, and how would you keep that explanation factual and well-grounded?
