What Is Collaborative Rating?
However, calculating this factor requires considerable CPU resources and can slow down CES. If this problem occurs, apply the rating to fewer documents (ex.: the 50 top ranking documents) (see Customizing Search Results Ranking).
Collaborative rating is displayed as a number of grey stars under each document (); whereas personal appreciation is displayed as a number of yellow stars (). Personal appreciation prevails on collaborative rating meaning that, once a document is rated by a user, its collaborative rating score is no longer taken into account during the ranking process.
Note: Collaborative rating is optional. You can enable it independently for each search interface in the Interface Editor (see Activating Search Interface Options).
