There was a recent change to the desktop search results whereby clicking the search box after a search has been performed causes the search box to move to the top of the page and the rest of the contents to blank out. I think there's a big UX issue here.
Typically, if I need to refine my search I double-click on a word in the original search phrase to change it. That no longer works, however. The first click causes the search box to move and also drops down a set of search results. The second click is registered as clicking on one of those results from the dropdown selector. So, I keep inadvertently clicking through to a search result I don't want. Then I have to go back to the previous page, single click the search box, wait for it to move, then go highlight the word I want to change.
As a secondary issue, I don't like the previous search results clearing out. I often use a phrase on one of the results to help refine my new search. With the results having cleared away I now have to memorize what was on the page. Since this is a new workflow, I typically have to search once, go to refine, fail, then go back to the original search term, memorize what I need, then try to refine the search.
I'd like to return to the previous search UI. I found it was considerably more usable and it better matches the experience with other search engines. Specifically, I don't want the search box to move on me and I don't want the current search results to disappear when I click inside the search box again.
