I really appreciated the insight into the KPI's they are using to measure the impact of Intent Search: * counted cumulative gain - a measure of ranking quality * query reformulations - a measure of search friction * complaints about search relevance * engagement with top search results It's great to be able to define concrete KPIs that have an objective impact on user experience.
