At least on my installation, the "refresh" button does not cause the "Search result detail" window to update. That button does refresh the main window showing search results. The mechanism I described (copy and repaste the URL in the address bar), however, does cause the "Search result details" window to synchronize with the main search result window. I am of the opinion that this is unexpected behavior since the "Search result details" window should always be in sync or at least display an error message when sync is impossible.
