  title: Ariba Guided Buying Search Shop With Facets
  summary: Search a shop with items and facets expanded, then refine the item list by a search term.
  description: >-
    A faceted browsing flow over the Public Catalogs Shop API. It retrieves a
    shop with both items and facets expanded so the caller can see the available
    filter dimensions returned from SAP Business Network, then issues a focused
    item listing using a search term to narrow the results. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
