In its simplest usage, `Model.find()` accepts a query document (a JSON object) as the first argument, then a callback. It returns an array of matches. It supports an extremely wide range of search options. Read more in the docs.

Modify the `findPeopleByName` function to find all the people having a given name, using < code > Model.find() -\> [Person]</ code >

Use the function argument `personName` as the search key.

```js

(getUserInput) =>
$.post(getUserInput('url') + '/_api/find-all-by-name', {
name: 'r@nd0mN4m3',
age: 24,
favoriteFoods: ['pizza']
}).then(
(data) => {
assert.isArray(data, 'the response should be an Array');
assert.equal(
data[0].name,
'r@nd0mN4m3',
'item.name is not what expected'
);
assert.equal(data[0].__v, 0, 'The item should be not previously edited');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
