A method and system is provided for automatically displaying a search-refinement user interface based on structure identified in search results in response to unstructured search queries. A list of search results obtained by a search engine is analyzed to determined whether a structure threshold is satisfied. If the threshold is met, then search-refinement options are displayed on a common display with the search results to allow the user to filter the search results according to the structure identified in the results. The user interface can receive filter and sort requests from the user to further refine the search results based on overlapping schema attributes or other shared-structure elements identified in the search results.
