Infoseek

Infoseek was a search engine founded in 1994 by Steve Kirsch. It was bought by Disney in 1998, and the technology was merged with that of the Disney-acquired Starwave to form the Go.com network.

Infoseek featured a very complex system of search modifiers, including boolean modifiers such as the most basic "OR" and "NOT", up to parentheses and quotes, up to being able to say that you want one word or phrase to appear within x number of words from another word or phrase.
