If anyone is interested in the type of work that goes on in my group at eBay, take a look at this blog post by one of my colleagues: https://www.ebayinc.com/stories/blogs/tech/making-e-commerce-search-faster/

It describes a 25% efficiency gain via a technique called index reordering. This is the engineering side of the work, I also work on recall and ranking.

Those long-tail gains are really nice, and the real win IMO.

Really nice work Jon, I have done some lookings in `tsv-utils`, really impressive tool. I readed the paper, will have some demonstration of those techniques using D ?

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.
