How to create a search system for a tree of javascript arrays

Yesterday, i asked a question about searching for arrays, i got an answer that contains the following code:

function searchDatabase(query) {
  // For each object in array
  for(var object of SampleArray) {

    // Get list values of object
    var lists = Object.values(object)

    // For each list of object
    for(var list of lists) {

      // For each item of list
     for(var item of list) {

     // Look for item matching query. Locally convert to lower case to
     // avoid case sensitivity issues
     if(item.toLowerCase().indexOf(query.toLowerCase()) !== -1) {
      return object
     }
    }
   }
 }
}

Here is my array

"Songs": [{
    "title": "", "Source": "", "SongArt": "", "artist": "", "explicit": false
 }]

I’m aiming to find a solution so i can search for a variable in the array like the “source”, and if it is found, then it will do a console.log(Found Variable);
