Querying a FeatureLayer with Angular JS
Hey there.
Im starting to develop a little app that it has to search a value in a feature layer and give the result in some html List and also make a zoom in a map with the current location (i would like to add the infotemplate from the feature).
Im programming with esri-angular api, but i dont find any example of :
1.- How to query data from a featurelayer
2.- How to make a zoom to the founded feature.
3.- Is there a way to not use this to add the feature layers and doing it through code?
<esri-feature-layer url="http://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/Heritage_Trees_Portland/FeatureServ..."></esri-feature-layer>
<esri-feature-layer url="http://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/Portland_Parks/FeatureServer/0"></esri-feature-layer>
Thanks in advice for ur help guys as always 
I just have this on my code:
Mapa.JS
angular.module('myApp', ['esri.map'])
.controller('MapController', function ($scope) {
$scope.map = {
center: {
lng: -71.51079005370974,
lat: -33.0324567956618},
zoom: 10
};
