Perch Search - Search results from a particular category

Hi There,

Is it possible to return a set of search results from a particular category?

Example. We have a blog for a client and within that blog they have a category called recipes. They want a search that will only return results from this recipes category.

Is this possible. I thought we could change the from path to something like 'from-path' => '/blog/category/recipes', but this doesnt work.

Any ideas?

Thanks Barry
