Searching mongodb with mongoose inside AngularJS app - angularjs

Question

Hello everyone am trying to search (query) the mongodb using mongoose in my AngularJS app. Am looking to have specific element. Can you help ? Any suggestion would make me advance. I need the general idea. Also I am new to mean
here is my angular code :
var app = angular.module('chirpApp', ['ngRoute', 'ngResource']).run(function($rootScope, $http) {
$rootScope.authenticated = false;
$rootScope.current_user = '';
$rootScope.signout = function(){
$http.get('auth/signout');
$rootScope.authenticated = false;
$rootScope.current_user = '';
};
});
app.config(function($routeProvider){
$routeProvider
//the timeline display
.when('/', {
templateUrl: 'main.html',
controller: 'mainController'
})
//the login display
.when('/login', {
templateUrl: 'login.html',
controller: 'authController'
})
//the signup display
.when('/register', {
templateUrl: 'register.html',
controller: 'authController'
})
//search
.when('/search', {
templateUrl: 'search.html',
controller: 'searchController'
});
});
app.factory('postService', function($resource){
return $resource('/api/posts/:id');
});
app.controller('mainController', function(postService, $scope, $rootScope){
$scope.posts = postService.query();
$scope.newPost = {created_by: '', text: '', created_at: ''};
$scope.post = function() {
$scope.newPost.created_by = $rootScope.current_user;
$scope.newPost.created_at = Date.now();
postService.save($scope.newPost, function(){
$scope.posts = postService.query();
$scope.newPost = {created_by: '', text: '', created_at: ''};
});
};
});
app.controller('searchController', function(postService, $scope, $rootScope){
$scope.posts = [];
$scope.posts = postService.get(text:"1223");
$scope.tiks=[];
$scope.newPost = {created_by: '', text: '', created_at: ''};
$scope.post = function() {
$scope.newPost.created_by = $rootScope.current_user;
$scope.newPost.created_at = Date.now();
postService.save($scope.newPost, function(){
$scope.posts = postService.query();
$scope.newPost = {created_by: '', text: '', created_at: ''};
});
};
});
app.controller('authController', function($scope, $http, $rootScope, $location){
$scope.user = {username: '', password: ''};
$scope.error_message = '';
$scope.login = function(){
$http.post('/auth/login', $scope.user).success(function(data){
if(data.state == 'success'){
$rootScope.authenticated = true;
$rootScope.current_user = data.user.username;
$location.path('/');
}
else{
$scope.error_message = data.message;
}
});
};
$scope.register = function(){
$http.post('/auth/signup', $scope.user).success(function(data){
if(data.state == 'success'){
$rootScope.authenticated = true;
$rootScope.current_user = data.user.username;
$location.path('/');
}
else{
$scope.error_message = data.message;
}
});
};
});
in the searchController am trying to query a specific post with text 123.
Here is my schema :
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var postSchema = new mongoose.Schema({
username: { type: Schema.ObjectId, ref: 'User' },
created_at: {type: Date, default: Date.now},
text: String
});
var userSchema = new mongoose.Schema({
username: String,
password: String, //hash created from password
created_at: {type: Date, default: Date.now}
})
mongoose.model('Post', postSchema);
mongoose.model('User', userSchema);
