Hi,
I'm Erick Guan, a 2nd student and wikipedian since 2008 who is interested in MediaWiki development.
In general, the goal of this project would be: redesign Special:SearchTranslations page, bugfix and alternative backend based on ElasticSearch. This made the Extension:Translate more powerful and easy to use.
And Wikimedia Language engineering team described one stop translation search in details in the GSoC feature idea page. Bugzilla, visual spec defines the exactly idea about what will it be and what we want to achieve. It's not hard to work on it and actually made this happen.
Here is my proposal: https://www.mediawiki.org/wiki/User:Fantasticfears/GSoC_2014_2#One_stop_tran...
