Advanced Query Syntax in Exchange 2013

Hi,

I have used AQS (Advanced Query Syntax) to find mails in Exchange 2010 using EWS in a custom .Net application that I have developed.

I tried to do the same for Exchange 2013 but AQS didn't work in 2013. Instead I found In-place eDiscovery search http://technet.microsoft.com/en-us/library/dd353189%28v=exchg.150%29.aspx. in 2013.

Can anyone please tell me whether Advance Query Syntax as described in this link http://msdn.microsoft.com/en-us/library/ee693615.aspx

supported in Exchange Server 2013.

Regards,

Gagan
