Thanks! So “archive” is “status.”
Here is what I can do. Search for Syria arrive at 3,248 hits. Press the refine link and arrive at the url (instead of search.php). Add the additional search variable archive (&archive=-2). This gives me 49 resources all of which, if I open them individually, have the status of Pending Submission. So far so, pretty much what I asked for, the ability to refine a search using status . . . I mean archive.
Then it gets a little complicated. Try and navigate the resources through the resource panel (view next result) and you end up navigating all the resources. Try to add the resulting search to a new collection and you end up with all 3,248 resources of the original search term.
