What is Database Notes about?

This document discusses how LIKE %query% in SQL performs a full table scan without using an index, similar to how MongoDB db.posts.find({author: /^h/i}) would search the entire collection without using an index, and how adding a sort to the query could allow MongoDB to use an index.
