Only searches when entered text contains word characters

[jsit]

Because this plugin is only triggered on word characters (let l:kw = matchstr(l:typed, '\w\+$')), if a string is entered that contains hyphens, for instance, tags aren't searched.

Would it be possible to re-implement g:asyncomplete_default_refresh_pattern and use that?

Otherwise, I'm finding that this works much better:

let l:kw = matchstr(l:typed, '[[:alnum:]_-]\+$')
