If I turn on the migration "July 2013 Breaking Changes" of my application, then email search will not work

Question

I use the search graph API to search users by email. Here is an example of how I do this:

GET https://graph.facebook.com/search?q=Sample%40gmail.com&fields=name%2clink%2ceducation%2cid%2cwork%2cabout%2cpicture&limit=2&type=user&access_token=... 

Before July 2013 Breaking Changes, it worked fine. As soon as I turned on violations, I started receiving HTTP 403, saying that the access token is invalid.

 HTTP/1.1 403 Forbidden Access-Control-Allow-Origin: * Cache-Control: no-store Content-Type: text/javascript; charset=UTF-8 Expires: Sat, 01 Jan 2000 00:00:00 GMT Pragma: no-cache WWW-Authenticate: OAuth "Facebook Platform" "insufficient_scope" "(#200) Must have a valid access_token to access this endpoint" X-FB-Rev: 798183 X-FB-Debug: lZPVbdTmZrCo+Bde/MNEXy/halUzQx7qIDW5aiZeT0g= Date: Mon, 29 Apr 2013 07:25:29 GMT Connection: keep-alive Content-Length: 120 {"error":{"message":"(#200) Must have a valid access_token to access this endpoint","type":"OAuthException","code":200}} 

As soon as I remove% 40 (@ sign) or part of .com from the request, I get normal HTTP 200 results. The problem is that this is not what I am looking for. I want to be able to search users by email as I could before.

Example queries executed :

 GET https://graph.facebook.com/search?q=Samplegmail.com&fields=name%2clink%2ceducation%2cid%2cwork%2cabout%2cpicture&limit=2&type=user&access_token=... GET https://graph.facebook.com/search?q=Sample%40gmail&fields=name%2clink%2ceducation%2cid%2cwork%2cabout%2cpicture&limit=2&type=user&access_token=... 

Answer 1

As 林果 皞 said. This is a bug in the graphics API. I filed an error here: https://developers.facebook.com/bugs/335452696581712

Answer 2

try FQL ?

SELECT uid, username, first_name, middle_name, pic, pic_small, pic_big, pic_square, last_name, name, email address, birthday, birthday_date, contact_email, current_address, CURRENT_LOCATION, education, hometown_location, languages, locale, profile_url, sex, work from the user where it contains (' [e-mail] ')

Answer 3

Email search works fine for me (token access is simply granted for basic permissions):

https://developers.facebook.com/tools/explorer?method=GET&path=%2Fsearch%3Fq%3Dlimkokhole%40gmail.com%26fields%3Dname%2Clink%2Ceducation%2Cid%2Cwork%2Cabout%2Cpicture%26limit%3D2%26type % 3Duser

Update :

Recently, the Graph API API Browser API application has already been included "July 2013 Changes." So, the example I showed above will no longer work.
