The Vote feature is used to assign a rating to a document. In eXo Platform, you can vote for a document via the 5-star rating. The more stars you select, the higher rating you evaluate.
Open the document for which you want to vote, then select on the Action bar.
The Vote Document form appears.
Rate the document by clicking the appropriate star level.
After a vote has been added, the rating will appear at the bottom of the document:
Avg. Rating: The average value of all votes assigned to the document.
Votes: The number of votes assigned to the document.
You can change your rating for a specific document by selecting the star level again and the rating system automatically updates and calculates your last rating.
