The search engine was born in a war zone. 🚀🔍 We investigate the history of Coordinate Indexing, a system invented by Mortimer Taube to organize millions of captured Nazi V-2 rocket documents. We break down how this manual system of "uniterms" laid the foundation for every modern search algorithm, proving that the internet's DNA is rooted in military intelligence.

1. The Paper Flood: We analyze the crisis. In 1945, the US seized tons of German technical documents. Traditional libraries couldn't handle the volume or the specificity. We explain how Taube's invention of "Post-Coordinate Indexing" allowed users to combine keywords (e.g., "Rocket" + "Fuel" + "Liquid") to find documents dynamically—the exact logic of a Google search.

2. The "Uniterm" Breakthrough: It’s not a card catalog; it’s a database. We expose the mechanics. Instead of filing a document under one rigid subject, Taube assigned it a unique number and indexed it under multiple single-word "terms." We discuss how this "keyword-based" retrieval system revolutionized information science by decoupling the content from the container.

3. The "Boolean" Legacy: We explore the connection. Taube's physical cards were the analog precursor to Boolean Logic (AND, OR, NOT). We discuss how this military necessity—finding specific weapon schematics instantly—evolved into the digital search engines that now organize the entire world's information.
