Simple suggestion for improvement

Hello,

Being relatively new to R, I often find myself searching for functions 
using help.search("term"). Why not have the command ??term invoke it in 
the same way as ?topic invokes index.search("topic")? Using a double 
question mark to invoke a wider search for a term seems relatively 
intuitive to me, and presumably would be trivial to implement.
