I've done a lot of searching and experimenting with this and can't make it work.  Basically I, like most, get a lot of email that isn't spam but isn't interesting.  I read the first line preview and then archive it with a swipe on my iPhone.This causes an annoyance because the phone archives it without marking it as read, meaning when I use the web app or my mail app, I get numbers beside various labels.If I search Gmail with the following filter:-label:inbox -label:trash -label:sent -label:spamthen it pretty much just selects messages I've sent to archive.  However if I then try to create a filter with that, Gmail changes it to label:spamevery single damn time.  All I want is to select only archived messages with a filter, and mark them as read.Anyone have any idea how to get around this?  There must be a way.  Thanks in advance.
