I experienced a strange problem with a SharePoint 2010 application. The new social features provide a tagging mechanism and these tags have a profile page where you can follow, view and generally find information about the tag.
As you can see from the image above the page is reporting no data available. Now this was puzzling as I had tagged several pages with this tag.
So I turned my attention to Search as other social features while installed are not enabled by default.
Trying to find content by this tag also resulted in no items
Navigate to the Search service application and browse to Crawled Properties. Firstly look for ‘key’ and make sure the TaxKeyword is included in search.
Commit this change.
Next is the tags starting with ‘tax’
Once these changes are made you need to re-crawl the content and profiles for these changes to propagate to the index.
Tag information is now displaying
