While reading and Idea and then hitting back in the web browser it should not clear the search term and essentially start the session over.

While searching for Idea's to vote for it is very annoying to have to start over each time you hit back in the browser. When you hit back it takes you back to the search for Ideas screen, clears the search. Then you have to start from scratch. This will lead to people just entering every idea instead of looking to see it it is already entered in some way.
