How to send a MVC Model in a Ajax Call

Question

Hi Experts 

I am facing challenges for posting a Model to invoke an action in a controler.

i have a main view where i make a web service call and with ceratin criteria and get the results.Once i have the results i am showing the results into a partial view as a pop up on the original view and then in the partial view pop i have  a search button which should search in the results shown in the partial view.So for this i need to send the model to the controller to search in the results set that is being displayed in the partial view.

Can this be achieved 
How can be this achieved ?
