title: Sharepoint 2010 Search - Auto add property to QueryString
body: <p>Have a bit of a difficult question which as far as I can see, no one has really managed to fix yet.</p>
  
  <p>Here's the scenario. Sharepoint 2010 EnterPrise Search Centre.</p>
  
  <p>I've created a custom Search Results Page. I want people who type any word in the Search box to only display results where the Value provided by the user matches with a specific Managed Search Property.</p>
  
  <p>Now I know a user can search for People with specific criteria by entering for example
  Continent:Europe in the actual Search Box. Sharepoint will refresh the page with the following added to the Query String: k=Continent:Europe and the results will only show people who are from Europe.</p>
  
  <p>So my question is : How can I fix this so that the user does not have to enter the Continent:Europe in the Search box and can just type Europe?</p>
  
  <p>Thanks</p>
