How to get data like CTRL+F, but query another spreadsheet

I have a large spreadsheet with many tabs that I want to keep in a secure location. I want to be able to query it, essentiallly exactly the way CTRL+F does, when set to "entire workbook", to be able to find cells that contain the search key, with a report out that shows at least the tab name. So, is there a way to CTRL+F but to apply it to a completely different workbook?
