We recently made some changes to our SharePoint 2010 website that included renaming several sites, including the site url. It seems that this caused us to lose the ratings that were associated with our pages.
It appears the rating lives somewhere though because our search filter using the rating refiner still recognizes that the pages have ratings. However, if you click on the page from the search results after filtering on a rating selection, the rating control shows 0 ratings when you get to the page.
The search index had been deleted after the migration and you can save new ratings on our pages.
We're wondering if anyone had any ideas on what might've happened with the old ratings? We assumed they were part of the meta data of the page and shouldn't have been affected by the site name/url change. Are they tied to the URL somehow?
