Understanding a search engine's inner workings

One of my favorite academic questions to ask people about search technology is, when do you think internet searching was invented? While the exact date is elusive, the answer is nearly always wrong—by several decades. Routinely, people reflect the common understanding that search technology was invented in the 1990s.

Actually, a search engine merely employs search query and indexing principles that were conceived and implemented decades before in a mainframe environment. Indexing, coupled with search queries, allowed early computer operators to quickly select relevant information from large databases in the infancy of the computer age. The Internet is simply a much larger database and a modern search engine is simply a much more robust and sophisticated search query tool.
