Greetings, fellow DNNers

I'm working with DNN 7's Search Module in a Products page, and it is dynamically returning results successfully (via AJAX).  

I've been able to limit the search scope to pages, but I actually need this (and only this) particular search module to be even more narrow-- ideally returning only pages tagged with "Products" as a result.

I know it's possible to open up the advanced search options as an end user and filter by tags, but I'm wondering if there is some way to tell the DNN Search Module in its initial configuration to search only for pages marked with the "Product" tag from the start automatically-- so the user won't have to do it?
