Hi,
Some of the OOB search results sources use {searchTerms?}. Conversations is an example.
I wonder what is the question mark at the end of the variable?
The variable I know and use is {searchTerms}
The answer is missing from the following articles:
- Keyword Query Language (KQL) syntax reference http://msdn.microsoft.com/en-us/library/ee558911(v=office.15).aspx
- Query variables in SharePoint Server 2013 http://technet.microsoft.com/en-us/library/jj683123.aspx
Thank you,

Clik here to view.
