@hannah you can do advanced filters like - and such
Theres advanced search operators for gmail's search, it's not *only* the search fields you get in the form, 1 sec

Actually 1 sec wtf there's no match for "inbox" here, did google really not add it
@hannah
urgh the search include/exclude thing being ignored...
also you can expand the selection of 50 to "all" by clicking the "select all <amount> of messages" when you try to select just 50, at the top bar
you may be able to apply a label to everything you have archived and from before a cutoff date, and then open your account through an IMAP client that will parse the label as a folder in its ui w/everything grouped together, and then mass-delete by nuking them through that application.
doing this in the gmail web interface is gonna going through the messages one page of results at a time, clicking select all, clicking delete, and then next page.
@hannah i haven't thought about this for a while, but `is:archive` and `before:[date]` still seem to work.
i _think_ is:archive and is:inbox are mutually exclusive, but, like, check me on that.
