For testing purposes I want to search through the media of the featured image in Wordpress. But it seems I can't activate the search through a JavaScript action.

The search DOM on the admin page is:

```
<input type="search" placeholder="Search media..." id="media-search-input" class="search">

```

I can change the value of the input field with:

```
// input text string
document.getElementById('media-search-input').value = "test string";

```

After changing the input value, no search is being done. I guess I have to trigger the search somehow, But I don't know how?

It seems I can't trigger the search with .click(), .focus() or .blur(). There's also no button to hit because WP has a live search functionality.
