AngularFire query on multiple fields
<p>I'm working on a project which needs to select data from <strong>Firebase</strong> on <strong>multiple fields</strong>. </p>

<p>I have a firebase database like this:</p>

<pre><code>[{
    date: "2016-01-29"
    done: false
    task: "hello world"
},
{
    date: "2016-01-29"
    done: false
    task: "hello world"
}]
</code></pre>

<p>Now I want to query all data with <strong>date</strong> is today and <strong>done</strong> is true.</p>

<p>I look around google for a while but there's nothing work. Is there any one can please help me to figure this out?</p>
