A human search engine is a search engine that uses human participation to filter the search results and assist users in clarifying their search request. The goal is to provide users with a limited number of relevant results, as opposed to traditional search engines that often return a large number of results that may or may not be relevant.

Examples of human search engines include Jumper 2.0, Sproose, NiteCo^[1], ChaCha Search, Mahalo.com, and the now defunct NowNow from Amazon.com.
