AngularFire query on multiple fields

I'm working on a project which needs to select data from Firebase on multiple fields.

I have a firebase database like this:

[{
    date: "2016-01-29"
    done: false
    task: "hello world"
},
{
    date: "2016-01-29"
    done: false
    task: "hello world"
}]

Now I want to query all data with date is today and done is true.

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

You can only query on a single property with Firebase queries. So either you'll have to do the rest of the filtering client-side or you'll have to combine the values into a single 'date_done' property.

[{
    date: "2016-01-29",
    done: false,
    date_done: "2016-01-29_false",
    task: "hello world1"
},
{
    date: "2016-01-29",
    done: false,
    date_done: "2016-01-29_false",
    task: "hello world"
}]

Now you can get all the queries that were done on January 29 with:

ref.orderByChild('date_done').equalTo('2016-01-29_true').on(...
