The [`Highlight.fields`](https://github.com/fullscale/elastic.js/blob/master/src/search/Highlight.js#L64-L80) function does not return anything and thus violates its stated return type [documentation](https://github.com/fullscale/elastic.js/blob/master/src/search/Highlight.js#L62). I think it's just missing the `return this;` line that the [other functions](https://github.com/fullscale/elastic.js/blob/master/src/search/Highlight.js#L105) have.
