Show breadcrumbs in search results (instead of space)

[denisemcg]

I noticed recently that the space is now displayed in the search results list. This is not required or useful when I have only 1 space. See the image on the left below.
What I would like is for the page breadcrumbs to display instead, i.e. the parent page(s).
Why? Sometimes I have a similar page, such as Export data, in multiple products but the search results doesn't identify the product. Therefore, I might have Export data four times in the search results, each one being a separate page, but users don't now which one they need. If they could see the parent page, they'd have more context and get the right information quickly.
