Admin Bar Backend Search by ocean90 puts WordPress backend search forms in the admin bar.
On the administration you can find different search forms. Some for contents like posts, pages, media or comments. But you have also one for plugins, themes and/or users.
This plugin will centralize all search types into one search form, which is placed in the new Admin Bar. You can change the type via a dropdown menu.
