Rating for End users
In the portal contents can be set as rateable. If it's set, as a user you can rate these contents.
In case of a rating enabled content you should see a control like this:
You can see the stars on the content, those are responsible for the rating. The blue stars are show the average rate value of the content.
How to rate
As an end user you have the opportunity to rate any content that has rating enabled on because you have permission for it by default. So if you click on any of the stars you will rate the content with that value. As you can see we have five stars here but this scale can be customized so there could be more or less star for rating.
When rating is enabled on a content a statistics panel can be enabled to see information about the rating on the content. If it is enabled you have to move your mouse over the rating stars to see this panel. You can see the cumulative statistics about the rating of the content for example the average rate value and the percentage values of the rates.
Search by rating
The portal has functionality for searching contents by ratings.
