Searching 'D' or 'dlang' makes difference to TIOBE index, but dlang gives better hits on Google

Just something for those who don't know it yet.

I was wondering how TIOBE index is calculated for programming 
languages. This is their definition:
https://www.tiobe.com/tiobe-index/programming-languages-definition/

And this is its grouping of search for either 'D' or 'dlang'

>D: D (confidence: 90%, exceptions: -"3-D programming" 
>-"DTrace"), dlang

This proves that there is no need to change official name of 'D' 
to 'Dlang' :)
