Php 如何使用Angular js传递url的搜索关键字，以及如何基于该搜索关键字检索结果

我想使用angular js显示搜索结果，当我们从自动建议中选择时，搜索关键字将通过url并显示特定的搜索关键字结果。我刚开始使用angular js，有人能帮我吗

js文件

   var app = angular.module('myApp', ['ngMaterial']);

    app.controller('myCtrl', function ($scope, $http, $q, GetCountryService) {

        $scope.searchText = "";
        $scope.Person = [];
        $scope.selectedItem = [];
        $scope.isDisabled = false;
        $scope.noCache = false;

        $scope.selectedItemChange = function (item) {
            //alert("Item Changed");
        }
        $scope.searchTextChange = function (str) {
            return GetCountryService.getCountry(str);
        }

    });

    app.factory('GetCountryService', function ($http, $q) {
        return {
            getCountry: function(str) {
                // the $http API is based on the deferred/promise APIs exposed by the $q service
                // so it returns a promise for us by default
                var url = "http://www.example/index.php/admin/default/searchcompanies?token="+str;
                return $http.get(url)
                    .then(function(response) {
                        if (typeof response.data.records === 'object') {
                           alert(response.data.records);
                            return response.data.records;
                        } else {
                            // invalid response
                            return $q.reject(response.data.records);
                        }

                    }, function(response) {
                        // something went wrong
                        return $q.reject(response.data.records);
                    });
            }
        };
    });
