How to filter two fields using item=>item

Currently my code works perfectly as the Search function searches the Name field. I now want the Search function to also filter through Clubs.

My current code is:

if(search && search !== $w('#searchInput').placeholder) {    
        var lowerCase
        var filteredSearch = originalRows.filter(item =>                 item.fullName.toLowerCase().includes(search.toLowerCase()));

I would like the same search function to search item.footballClub

So if I search “Bar”, then it should filter BOTH the name “Bart” and the club “Barcelona” as an example. How can I do this as simply as possible?
