ab

Solr search ranking comparison app. Seed it with multiple alternative dismax queries, and let users rank result sets from a randomly selected pair. Result sets are checked for difference before being displayed.

Statistics are available at /handlers. Switch handlers on and off, and add new ones at /handlers/admin.

Setup

Install dependencies:

$ gem install --no-ri --no-rdoc rack sinatra sinatra-static-assets sinatra-flash datamapper dm-sqlite-adapter haml nokogiri warden bcrypt-ruby

To set up the sqlite3 database, set up an admin password, and seed some handlers:

$ ruby run/setup development

$ ruby run/setup production

You don’t have to populate with the default handlers, but if you don’t
you could experience errors until you’ve added handlers…

App settings are in settings.rb in application root.
