I've searched high and low for an answer to this but to no avail. As a book seller, I would like to display book title, author, and sku in the predictive search. Right now, it will search by author but will only display the book title, not the author with it. I'm also not sure which Liquid file to look in to check out the current code situation. Please let me know if you have an answer to any of this. Thank you!
This depends on your theme/search app you're using. If you share a link to your shop ti will be easier to suggest something.
For Empire, you'd need to change the ProductContent function inside empire.js asset, it's not in the liquid code.
