Multiple results in People Search in SharePoint 2010
I had an issue in my lab server with User Profiles in SharePoint 2010 (big surprise!). In my troubleshooting, I had added multiple sps3://servername start address entries in my Content Source. I was troubleshooting and added the extra entries with the port and alternate access mappings variations. I solved my other issues with the User Profile service application and with search. I forgot to remove those extra entries. I removed the extra two entries and kept just the sps3://servername. It doesn't need the My Site host port or anything. Here's how to get there: Central Admin>>>Application Management>>>Manage Service Applications>>>highlight the search service application and click Manage.>>>Content Sources>>>remove the superfluous entires in the Type start addresses below section>>> click ok
