Support CJK searching

[typed-sigterm]

Docfind only supports whitespace-separated text now. CJK (Chinese, Japanese, Korean) don't use whitespaces to split words, so docfind can't work.

Does it only works for english?

docfind/core/src/lib.rs

Lines 121 to 125 in e6ee50a

	let stop_words = include_str!("../english.stop")
	.lines()
	.filter(|line| !line.is_empty() && !line.starts_with('#'))
	.map(|line| line.to_lowercase())
	.collect::<HashSet<String>>();

Yes obviously
