Thanks! Yes, that was a really nice result. No demos of it though 
(and it wasn't written in D).

Another paper that might be of interest: "The Architecture of 
eBay Search", 
http://sigir-ecom.weebly.com/uploads/1/0/2/9/102947274/ebay_search_architecture.pdf, published in the SIGIR 2017 e-commerce workshop.

And, there's some really cool work by one of my colleagues here: 
https://github.com/simongog/sdsl-lite. It's a set of "succinct" 
data structures, a set of very space efficient data structures 
and algorithms.
