WiseNut
WiseNut was a crawler-based search engine owned by Looksmart. It debuted as a beta in July 2001 and was officially launched in September 2001. It used its own database, and when it started it was highly regarded by a number of critics. WiseNut introduced a fresh database and relevant hits. Like Teoma, WiseNut automatically clustered search results, a technology called WiseGuide.
