Fusion was implemented at Foot Locker to improve the speed and scalability of their search capabilities. It helped reduce indexing times from 1 hour to 5 minutes, enabled A/B testing and experiments, and provided more dynamic faceting and keyword handling. Customers experienced a 0.25-1% increase in conversion, 1-2% increase in revenue per visit, and 4% decrease in null search rates. Future goals include enabling dynamic relevancy using analytics, geospatial search, multi-lingual support, and expanding to Europe and Asia-Pacific markets.
