How do I query a database with AngularJS's $resource factory for a specific set of rows?

I'm building an app using AngularJS and the MEAN Stack, and was wondering if it was possible to use the $resource factory to query a MongoDB database for a set of rows that have a certain value in one of their columns.

For example, if I wanted to build a Todo app, and I had a table with a column containing a persons username and a column with a string that had a reminder, is it possible to query the database for all the rows that have a particular username in the username column? Or, do I have to do something like this:

Todo.service.ts:

export function TodoResource($resource) {
    'ngInject'; 
    return $resource('/api/todo/:query', {
        id: '@_id'
        query: '';
    });
}

app.js

var list = [];
this.Todo.query().$promise.then( (data) => {

        for(let datum of data){
            if(datum.userName == email){
                list.push(datum);
            }
        }
    });

In this sample case, I'm not really querying the database, just getting the entire table and filtering the results by myself. Is this the only way to do it, or can I directly query the database?
