What this post added

This post details the technical implementation of a Boolean expression simplification engine for MongoDB queries. It describes the adaptation of the Quine–McCluskey algorithm and Petrick's method, the use of bitset representations for efficiency, and the challenges and solutions encountered in handling MongoDB's unique logical operators and negation semantics. The post also provides examples of performance improvements achieved through this simplification.
