I'm trying to use "searchContacts" method of the Google People Apis to search contacts by phone number but the result is always empty.
If I set the name of one of my contacts in query paramters, It works fine. If I set the phone number in the query parameter, no result is returned to me.
I also trying to use "The test panel" in the Google documentation page (https://developers.google.com/people/api/rest/v1/people/searchContacts) but I have the same end.
Is this possibile? If yes, How should I set the query parameter?
thank you
