    $\begingroup$ There is an example like this in the documentation page on Information. Typing "?" in help is useless :( (it does not bring you to Information). Also the syntax is so special that you cannot do something like Hold[?*Q]//FullForm to find out what function is being used. So I figured I'd post this. $\endgroup$ Commented Mar 7, 2013 at 14:11
  • $\begingroup$ Of course, not all of these are querying functions. EllipticNomeQ[], LegendreQ[], and MarcumQ[] are examples that spring to mind. $\endgroup$ Commented Apr 16, 2013 at 13:24
