Definition
From the Wikipedia:
"A distributed search engine is a search engine where there is no central server. Unlike traditional centralized search engines, work such as crawling, data mining, indexing, and query processing is distributed among several peers in decentralized manner where there is no single point of control." (http://en.wikipedia.org/wiki/Distributed_search_engine)
SearchTools.com offers a useful introduction to the concept of applying peer-to-peer to search, and a few references to projects current at the time, but the page states that it's not been updated since 2012.

InfraSearch (defunct)
In April 2000 three programmers built a prototype P2P web search engine based on Gnutella called InfraSearch. It was meant to run inside the participating websites' databases creating a P2P network that could be accessed through the InfraSearch website. InfraSearch was acquired by Sun Microsystems in 2001 to become part of the search system for the open source https://java.net/projects/jxta/ JXTA] project.Sun, and most its various subsidiaries and open source projects, was acquired by Oracle in 2009. Sadly, InfraSearch founder Gene Kan passed away on June 29th, 2002.
Opencola (founding company defunct)
On May 31, 2000 Steelbridge Inc. announced development of OpenCOLA a collaborative distributive open source search engine. It runs on the user's computer and crawls the web pages and links the user puts in their opencola folder and shares resulting index over its P2P network. Steelbridge was renamed Opencola, and the Opencola company was sold to the Open Text Company in 2003, after releasing Swarmcast under the GNU GPL.
YaCy (GNU GPL)
On December 15, 2003 Michael Christen announced development of a P2P-based search engine, eventually named YaCy, on the heise online forums. As of the January, 2016, the latest stable version was 1.8, released September 16, 2014.
In February 2001 Wolf Garbe published an idea of a peer-to-peer search engine, started the Faroo prototype in 2004,[10] and released it in 2005.
Wowd
Some time in 2006 Borislav Agapiev started thinking about a distributed search engine. Then on October 20, 2009 he publicly launched Wowd.
