StubHub, an eBay company, is the world's largest ticket marketplace, enabling fans to buy and sell tickets to tens of thousands of sports, concert, theater and other live entertainment events. StubHub uses Solr and Lucene to enable fans to search for entertainment by event type, date, location, venue, and price. Much of the faceting seen on the Browse and Search pages is direct Solr faceting. According to the site architect, reimplementing search based on Solr reduced their hardware needs over 50% and have improved page response times by 30-60% as compared to the old architecture (a mix of very old CF code for the browse pieces, and a couple GSAs for the search pages).
