The SharePoint People search works very well out of the box but it has one flaw , it displays more than people when you do a people search , it displays documents related to those people as well !
When you search for a users , say Edward. It starts with displaying all of the document that Edward has shared in his MySite and then it displays all of the documents in other users MySite that have the word “Edward” in it. This is an annoyance more than anything because it shows the users with the first name Edward right at the bottom of the search , and this really is what you are searching for.
To eliminate the display of user shared documents from being displayed when searches are made for people , I created an exclusion rule for this URL http://my***.com/personal/* this removes all personal site information from being displayed in the searches for people. This exclusion was created on the Portal_Content Index.
You get to it here : Site Settings —> Configure Search and Indexing –> Portal_Content –> Manage Rules to exclude and include content.
Note : This removes the Personal documents from being displayed in the search for All Sources as well as it uses the same content index to search through documents.
If you are wondering the exlcusion rule for http://my**demo.com/*.aspx is in place by default. The reason this exlcusion is in place is so that your index remains clean of supporting files that are a part of most websites , like images ,and client-side java script code.
Messaging and Collaboration 
Link exchange is nothing else but it is simply placing the other
person’s webpage link on your page at proper place and other person will also do same for you.
