[Plugin: Dave's WordPress Live Search]

I love this plugin, I’d just like to be able to add one more feature:
When the homepage loads, I’d like to be able to display all posts on the site within the livesearch results. So instead of having no results displaying, I’d like to have all results displayed.

I’ve had a go at implementing the code from this post:

but without success 🙁
