We like the new search as well. It's nice that you can have the results framed in a page of you own.
We found that you can put 2 search boxes on a page ( used 2 for a website that has both Spanish and English relevance).
But, while it lets you paste the 2 different search results code on the same page's html, when you test it, it takes forever and shows the same results twice. So, we reverted to 1 results area on a page and let it catch the results of either search.
Anyone else tried this?
