Mixi is one of the largest social networking services in Japan, providing various communication services for over 14M monthly active users. The latest internal mixi project is to replace the in-house search engine with Apache Solr. This session covers two topics; a simple packaging system for Solr that eases the installation process and daily operations, and implementation of a "Did you mean" facility for Japanese queries using a log mining tool. These tools have been released as OSS projects.
