People API searchContacts using google people service - google-people-api

Question

I have tried adding a new contact using Google People API with PHP client people service and it worked fine. I have used following code,
$service = new Google_Service_PeopleService($client);
$person = new Google_Service_PeopleService_Person();
$name = new Google_Service_PeopleService_Name();
$name->setGivenName($_name);
$person->setNames($name);
$phone1 = new Google_Service_PeopleService_PhoneNumber();
$phone1->setValue($_phone);
$phone1->setType('home');
$person->setPhoneNumbers($phone1);
$exe = $service->people->createContact($person)->execute;
Now I want to check if particular email already exists so tried searchContacts method of API. It works fine in API explorer.
ref:
https://developers.google.com/people/api/rest/v1/people/searchContacts
But when have tried with following code,
$service = new Google_Service_PeopleService($client);
$optParams = array('query'=>$_email,'pageSize' => 10, 'readMask' => 'emailAddresses', 'key'=>'XXXX');
try{
$rslt = $service->people->searchContacts($optParams);
} catch(Exception $ex) {
echo $e->getMessage();
}
i am getting following error,
PHP Fatal error: Call to undefined method Google_Service_PeopleService_Resource_People::searchContacts()
Looking at the error i am sure that the way to call the method is wrong. I have searched but not able to get proper documentation in guiding in that direction.
Any help will be appreciated.
Thanks

Looks like we cannot call searchContacts using people service object so i have used curl json to get it worked. I have used following code if anyone needs.
$url_parameters = array('query'=>$_email,'pageSize' => 10, 'readMask' => 'names,phoneNumbers,emailAddresses,organizations', 'key'=>'XXXXX');
$url_calendars = 'https://people.googleapis.com/v1/people:searchContacts?'. http_build_query($url_parameters);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url_calendars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer '. $access_token));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$data = json_decode(curl_exec($ch), true);
$http_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
if($http_code != 200)
throw new Exception('Error : Failed to search contact');
return $data;
