Maybe I'm not understanding the search functionality correctly, but in the frontend as demo/demo and going to User Control Panel > Orders, just about all my searches in the searchbox up top come up with no results.
For example, on the demo site, order Y21 has the product "fuse box". Searching for "fuse" yields zero results. I also tried terms from other orders: "sneakers", "shoes", and "ACME" all come up with no records.
Searching order numbers (e.g. "Y21") seems to work. But I'm confused because searching for "17" brings up order T17 (OK), but orders that don't even have "17" in them also come up. How does the search work?
