search_catalog
Start a text search in the Global Catalog using the UCP Playground's current filters, buyer context, language, currency, and page-size settings. Use for a shopper's product query, not for a known product id. Results arrive asynchronously: after calling, wait for completion and call get_search_results. This opens the active session and does not add anything to the cart.
