Adjusting Search

Just a shot in the dark here…

I've got an inventory of many beds. Each bed only has the name 'bed.'

When 'beds' is entered into the search bar, nothing comes up… naturally.

I know we can add extra search terms, but I'd like to avoid that if possible.

The category is 'beds.' I'd like to somehow include the categories and subcategories in the search results.

Not the names themselves, but the items within.

Thanks in advance for any advice.
