Hey! First of all, amazing work on Fuse.js. I've moved my search functions from Algolia to a completely front end solution using Fuse.

Comparing Fuse and Algolia, I've encountered a few differences which I believe could be easily improved.

Let's take the following data set:

[
  { title: 'Alert', subtitle: 'Variants' },
  { title: 'Button', subtitle: 'Sizes' }
];

Searching using the following search string: Alert Variants or Button Sizes will yield an empty results array.

Algolia would split the search string and identify the two keywords in the two different search keys, title and subtitle.

I know the current behaviour might be intended, but it would be nice to add an option to split the search string by the space separator and use both words individually.
