Currently I'm trying to search through my rather large email archive on Gmail.
Unfortunately the words I like to find also occur in almost any email footer as the signature text.
While I understand that there is no entity type "signature" in a plain email body, it seems that Gmail is still (limited) capable of detecting signatures (and collapsing them with those ... buttons).
My question:
Is there a search operator to tell Gmail to search for text but omit the signature?
