OT: Indexing reordering in the eBay Search Engine

[Jon Degenhardt]

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.
