Stack Overflow Search — Now 81% Less Crappy - Blog – Stack Overflow
Although our de-crapifying efforts have been noble and heroic (well, in my mind, anyway), we’ve clearly begun to exceed the scope and scale of what SQL Server search can do for us.
That’s why I’m pleased to announce that as of today, we have switched all of our search functionality network wide from SQL Server to Lucene, or more specifically, the Lucene.NET flavor.
