Search function that iterates through an array and returns the values matched init also in the child object

I’m trying to search an array of objects with objects that are nested in, so for example i have this array:

[
{
 website: 'Stackoverflow',
 info: {
  "extension": "com",
  "ssl": true
 }
},
{
 website: 'Faceoobok',
 info: {
  "extension": "com",
  "ssl": true
 }
}
]

So I want to search all fields, and then also search the object inside and return an array with the method filter, also the char cases won’t matter, it needs to return the object in the array even for example Stackoverflow is not the same as stackoverflow with the casing methods that come with JS.

Here is what I’ve tried, and It searches the objects and returns them but It doesn’t search the object inside, what I mean is for example it searchs the website, but not the .info:

const searchMachine = (arr, query) => {
        let queryFormatted = query.toLowerCase();
        return arr.filter((obj) =>
            Object.keys(obj).some((key) => {
                if (typeof obj[key] === 'string') {
                    return obj[key]
                        .toLowerCase()
                        .includes(queryFormatted);
                }
                return false;
            })
        );

>Solution :

You could take a closure over the wanted string and use a recursive approach for objects.

const
    searchMachine = (array, query) => {
        const
            check = (query => object => Object
                .values(object)
                .some(value =>
                    typeof value === 'string' && value.toLowerCase().includes(query) ||
                    value && typeof value === 'object' && check(value)
                ))(query.toLowerCase());
       
        return array.filter(check);
    },
    data = [{ website: 'Stackoverflow', info: { extension: 'com', ssl: true } }, { website: 'Faceoobok', info: { extension: 'com', ssl: true } }];


console.log(searchMachine(data, 'stack'));
console.log(searchMachine(data, 'com'));
