So stupid it even returns trashed and unpublished items! Useless. ExtnBakers Ajax search (not free) is pretty good but hard to put the modal where you want it.
Other ideas?
update: it's me that's brutish and dumb - I poked around quite a bit and found a way to create filters enough to exlude categories and articles older than a certain date. This gets me 90% of the way there. It's kludgy and non-intuitive though.
update2: brutal. The remaining 10% is trial and error, tweak content map, re-index (don't clear the index or you'll wipe out the content map), try and err some more, rinse, repeat, repeat, repeat. My ExtnBakers test worked perfectly on one - one! - try.
