[REQUEST] Fuse.js to support many more languages

[yuis-ice]

I believe implementing the search engine Fuse.js as a third search engine option available for the extension would be great, since it doesn't only enables many great features the library has, but it also enables the extension to allow many more languages, such as Chinese (mandarin), Korean, Japanese, and so on. I hope soon we can see the feature. Greetings.
