Based on the blog post serie algolia has done, they do not use something like wiredtiger. So I was fully wrong. They have fine tuned datastructures for every problem they encounter for indexing and querying. https://blog.algolia.com/inside-the-algolia-engine-part-1-indexing-vs-search/ Anyway, outside the far reaching goal of achieving concept search, I find wiredtiger handy+good enough that's why I use it. That's said if I need to get a living from my free coding I will not use wiredtiger. Best regards, Amirouche
