Wikipedia founder Jimmy Wales launched his open source search engine, Wikia Search, for testing on Monday, according to Ars Technica. (Wikia is not affiliated with Wikipedia.) The search engine, which some have labeled a "Google-killer," will be run on open source backend systems based on Grub indexing.
Wikia acquired the Grub indexing system and released it under an open source license in July 2007.
When Wikia Search was announced, Wales said he wanted to make "a political statement about transparency and openness." To that end, any user will be able to rank search results, and even the search algorithms will be open, says Ars Technica, so that "anyone with a bent for coding can get their hands dirty."
