How to highlight a found word using Sunspot?

I want to highlight the words found in the text, for example, as shown here .

As far as I know, I should follow these steps:

1) In my model, I have to add a parameter :stored => trueto the field that I want to highlight:

searchable do 
    text :title, :stored => true
    text :description
end

2) In my controller, I have to declare which field I want to highlight:

def search
    @search = Article.search do
        keywords params[:search] do
            highlight :title
        end
    end
end

3) In the view, I'm not sure what to do, I tried this:

- @search.each_hit_with_result do |hit, result|
    %p= link_to raw(hit_title(hit)), article_path(result)

This is what the method does hit_title:

def hit_title(hit)
    if highlight = hit.highlight(:title)
        highlight.format { |word| "<font color='green'>#{word}</font>" }
    else
        h(hit.result.title)
    end
end

But it does not work as expected, it always highlights the first word of the title, even if the search word is at the end of it.

Is there an easier way to do this?

Do you use substring search? I have the same problem, and I realized that including the substring in the match using the sunspot wiki tutorial led to this problem.
