The problem is if you have a non-auto-run search with embedded subsearches, you can either use the search button on each embedded subsearch (which is ugly and makes you click each one when changing filters) or you can use auto-run on the subsearches (which causes them to re-run whenever you change filters, which is not what you want). I think if you have a embedded subsearch within a non-auto-run search in inline (open) mode, the subsearches should only re-run when the parent search button is clicked, regardless of the auto-run setting of the embedded subsearch. The search button shouldn't be shown on the embedded subsearch if the parent search has a search button (but it should still be shown if the parent search is auto-run).
