REAL-TIME SEARCH TUNING

Embodiments are directed to dynamically tuning search result rankings to control how the search results are presented in a user interface and to dynamically updating search result rankings based on tuning inputs. In one scenario, a computer system receives search results with associated search result attributes. The search results are displayed within a user interface according to each search result's determined ranking. The computer system then receives a tuning input at the user interface. The tuning input indicates that a search result ranking model is to be adjusted for various specified search result attributes. Moreover, the search result ranking model determines how each search result is ranked. The computer system then dynamically updates the displayed search results as the search result ranking model is tuned for the specified search result attributes. The dynamic updating includes repositioning, adding and removing search results according to the determined ranking for each search result.
