Hidding the search pane

[vamp07]

I am starting to use the hide function for many of my windows. I notice that as the help file says, an esc will hide the window when I am finished with it. When I do a search the children/results window seems to get pinned and once I select the document I want to work on an escape will minimize the app instead of hiding the window. Am I doing something wrong? Is there some other way to get that window hidden and get the cursor into the item detail window?

Thanks
