How to search for people in Google Plus using email?

e.g. this query never returns anything:

https://www.googleapis.com/plus/v1/people?query=[email_address]@gmail.com&key=MY_KEY

I tried a db of a thousand emails at least,

Also I have an account with very strange name, when I search by name I get the result, but with email I don't , I tried to url encode the email but still it didn't work.

Answer 1

The email address must be set as a public field in the user's Google+ profile to be able to search and find that entry. The people.search method only searches public fields.
