Filter entries in CP by Author How can you filter entries in the CP by Author? I assumed entering something like author:tdavis (where tdavis is my username) would do it, but no results returned. I also tried substituting id for username.
For Craft 3, at least for now.

1) Make a custom plugin
2) Add event to modify the query in control panel

// Register element query prepare event
Event::on(ElementQuery::class, ElementQuery::EVENT_BEFORE_PREPARE,
    function(Event $event)  {
        if (Craft::$app-&gt;getRequest()-&gt;getIsCpRequest()) {
            if ($event-&gt;sender-&gt;elementType === 'craft\elements\Entry') {

                if(isset($_POST['criteria']['search'])&amp;&amp;strpos($_POST['criteria']['search'],'author')!==false)
                {
                    $email = explode(':',$_POST['criteria']['search']);
                    if(isset($email[1]))
                    {
                        $user = User::find()-&gt;email($email[1])-&gt;one();

                        if($user)
                        {

                            $event-&gt;sender-&gt;query-&gt;andWhere(['authorId'=&gt;$user-&gt;id]);  
                            $event-&gt;sender-&gt;subQuery-&gt;andWhere(['authorId'=&gt;$user-&gt;id]);  
                            $event-&gt;sender-&gt;search = null;
                        } 
                    }

                }
            }
        }
    }
);



So when you type author:[Email] it can fetch in the CMS.
