yourbang Outvi V طوّرها

This is an extension which aims at implementing a local version of Duckduckgo Bang.

Due to the limitation, a space is needed between "!" and the keyword, like:
! baidu what_you_want_to_search

There are several built-in search engines (namely Baidu, Bilibili and Chinese Wikipedia). You can also add your own search in the option page by editing the JSON string.
