I like the search window. I'd like it more if the original pop-up message told you where the items were located, but the window (once I'm used to it appearing!) is more useful than the text log messages for me. I don't have a lot of screen space so I can't set the text log window very large, and I actually can't see the entire search results without having to click over to the log and expand it to see where the items are - unless I want to know about collectibles, which I generally don't.

But yes, an option to choose between the new and old search formats would make sense.
