How to save a search result?

I am working on my personal website where I want to save the search result of my clients, limited to this particular session .

I use the PHP platform and Javascripts .

Here is an example of what I'm looking at for sure:

It saves your previously found domain name for this particular session so that the user can make a decision by comparing these results.

Thank.

EDIT - Good Thanks for all your answers and suggestions.

But if you notice the example above

It looks like a script , loading new content on the same page without updating and keeping the previous content search <div> as it is.

How to achieve this using javascripts or some kind of div layer ????
