Facebook Graph API: Any constrains to the query string length when making a GET request to https://graph.facebook.com/?

Does anybody know if there are any constraints to the query string length when making a GET r开发者_开发知识库equest to Facebook graph API? So far I've not encountered any problems but it's very important to know if there are any constraints or limitations.

Thanks, -Ali

From a comment from the Paging section of the Facebook API docs: it is helpful to know that the maximum number of results we will fetch before running the visibility checks is 5,000. That was for FQL, but I'm assuming the same limits apply to the Graph API. So you can't get more than 5000 results at a time
