This filter can be used to wrap <span class='highlight'> around anything you want to highlight in a block of text. For example, if you had 'foo bar foo baz' inside the context variable MYTEXT, you could do {{ MYTEXT|highlight:'foo' }}, and "<span class='highlight'>foo</span> bar <span class='highlight'>foo</span> baz" would be returned.

How you style the highlight class is up to you.

@register.filter
def highlight(text, word):
    return mark_safe(text.replace(word, "<span class='highlight'>%s</span>" % word))
