More useful matching

Hi,

while using this fine tool for a while now, I miss a matching feature from the rest of helm. When entering multiple words, I would like to see all lines that contain all of these words - in any order. E.g., when giving "soup eel", I want to see the entry for "eel soup". This would make it possible to narrow down a long list of candidates by giving more keywords without having to know how the exact dictionary entry looks like.

Do you agree that could be useful?

@thierryvolpiatto Is this possible at all with the current implementation? I guess it's just the match plugin that I'm missing. Any chance to get it work here?

Start by reading the current match plugin and implementation mentioned in the issue, then reproduce the multi-word query behavior with "soup eel". Done means a query matches entries containing all supplied words in any order, including "eel soup".
