The MeTA search and ranking demo is currently located at

The search engine is over Wikipedia articles with article titles as metadata. Selecting a ranker from the dropdown on the left of the search bar changes the ranking function that is used to score each document. The numbers to the right of each document are the score that the ranker has given it. Clicking on a link will open the respective Wikipedia article.

The demo code can be found online on GitHub in the MeTA toolkit organization. It makes use of MeTA’s (still experimental) Python bindings to create a simple web application.
