PLURIBUS    The search engine where your opinions count
Type your query: 

E Pluribus Unum: Out of many, one.

Pluribus is a search engine that remembers which pages its users like and which they don't like
It then uses that information to return high-quality, filtered results. 

Out of the opinions of many users, Pluribus constructs one coherent list of results. E Pluribus unum. 


How exactly does Pluribus rank its results?

When a user types a query, Pluribus submits it to Metacrawler, a search engine that combines results from other engines (including Altavista, Excite, Lycos and Yahoo!). Once it has those results from Metacrawler, Pluribus assigns a score to each page. 

The total score of each page (shown in black next to it) is a combination of: 

  • The score assigned by Metacrawler. This score reflects the closeness of the page to the user query. Metacrawler scores range from 0 to 1,000 points. (in green
  • How much previous users have liked this page (in the context of the same query). A user can vote for a page by selecting it. Each vote increases the score of a page by 100 points. (in red
  • The number of times that the page should have been selected. Pluribus expects pages presented at the top of the page (`better pages') to be selected more often than other pages; each time a page is selected, Pluribus subtracts some points from all those pages that were not selected, subtracting more points from highly-ranked unselected pages.
