Include exhibitPage parent exhibit in search results

While theming our Omeka Classic search results page, I’ve been asked if it is possible to include the parent exhibit name for each exhibitPage that is returned by a search query.

But I’m not too familiar with the global functions, hooks, etc (though I am starting to learn!). I would be really grateful to anyone who can give me an example of how to do this, or even a few hints about the right way to go about it.

We’re using Omeka 3.1.1 and I have copied the Application search results page to search/index.php within my theme directory. Our search is configured to only show Exhibits and exhibitPages, no collections or items.

Thank you in advance!
