I try to put at least 1 tag on each e-mail that comes in, but sometimes I miss some.Is there any way to search for all untagged e-mails in Gmail (or all e-mails with just the Inbox tag)?Right now the only way to find GMail e-mails with no tags (or with only the Inbox tag) is to scroll through my list of all e-mail and look for myself...terrible.I would like a way to get a list of all e-mails with no tags (or with only the Inbox tag).  I have tried a search term with -[Tag1] -[Tag2] -[Tag3] [...] with - in front of all of the tags I use, but that does not work.  If it or something like it did work, even being while long and awkward, I would still use it since it would be better than what I currently have to do!Edit:  I originally typed this out referring to tags, the non-GMail-centric word for labels.  Right before submitting I remembered the GMail-centric term and changed those words to labels before submitting the question.  I have now put the question back to the original way I wrote it so that people searching using search term tags (like I did, which is why I did not find How can I filter my Gmail messages that aren't labeled?) will find an answer.
Search GMail for e-mails with no tags (labels) (or just the `Inbox` tag)?
