you need to create a single.php page as described here
http://docs.wp-pizza.com/developers/?section=wppizza-markup-single-single-php

(although this is mentioned in the widget, the link i put there – which is meant to point to the page above – is actually wrong, i need to fix that )

update to the above:
it transpires there is no documentation I wrote on that subject , simply because there are no provisions for this (yet)

i spent most of the day today trying to find a way to do this automatically in some way shape or form to integrate this without having to edit/mess around with theme templates.
Alas, there does not appear to be a way to do this without editing theme files (similar to the single page templates in the link i posted above) or, to be more accurate, I could not find any universally usable way to do this without the need to edit theme (search) templates.
Note: this kind of makes sense up to a point , as themes should have control over layout and plugins should add the functionality. Problem being here that wppizza is a bit of a hybrid on that front.

Offshot being, I have to write and add a function or two to the plugin and add some documentation to the docs regarding how to edit/amend the search template

I am fully committed to do this, but it will take a day or 2 to do to add to the plugin and writing the docs

please bear with me
