1. Create a user control, which is taking the Url query parameter SearchQuery.
If you notice, when you search for a term, this term is transmitted to the Search Results page with as GET paramater. Let me give you an example:
I search for "something", and my URL looks like:
2. Once you get this parameter in your user control, you can do what ever you want with it - for example, save it in a text file, or in a database. It is up to you.
I hope this helps you.
