well is this still up-to-date or removed during the builds?
got 4.4.5 running here still and did a test: searched for a couple of very common terms, noted down the amounts of results after search was finished and looked in again after 3 hours.
not any search result changed.

so i must assume the 45 mins requery was removed for whatever reason

moreover for the wishlist: would be nice to have a /global/ search that can repeat searches for all my search tabs (usually 30 - 40 at a time)
currently i need to repeat every search manually...
pain in the neck but it's me who want the rarities not the rarities who want me ... so i will take this pain if there's no other way
(and maybe will never be)
