I tried a couple test queries:
> lambda decay to function pointer c++
I get some FSF pages and the wikipedia for Helium?
> std function
I get... tons of Rust docs?
> std function c++
All rust docs? The wikipedia page for C++??
Interesting idea, but this seems like it would be the primary failure mode for an idea like this: as soon as you are researching outside of the curator's specializations, it doesn't have what you're looking for. Yet these results would both be fixed simply by adding cppreference.com to the index. Let's try and give it a real challenge:
> How to define systemverilog interface
And as I might expect, I get wikipedia pages. For "Verilog", for "System on a Chip" and for "Mixin".
1st google result:
> An Interface is a way to encapsulate signals into a block...
Working as expected
