Adding a Second 2nd Comment to resource does not appear in search results

1. Create a resource, such as http://beta.curriki.org/xwiki/bin/view/Coll_tsherman/MobileThinkingGamesforAppleandAndroid
2. Add a comment with 5 stars
3. Go to search and very comment with stars show up in results
4. Go back to resource and add a second comment with 1 star. I added the second comment as a different user.
5. Go to search and find the resource again.

Bug
The resource should appear showing there are 2 comments and the average rating is 3 stars. But it is only showing the results from the first comment.

I did not try adding a third comment.

I was on Chrome but checked it in FF too.
