[xml] Official Site Search Service Unavailable

[林博仁 <buo ren lin gmail com>]

I would like to search the seemingly available libxml2 GitHub mirror
on http://xmlsoft.org today and the search query returned the
following error message:

    Could not connect to the database: Can't connect to local MySQL
server through socket '/var/lib/mysql/mysql.sock' (111)

Best regards,
