Is there a way to use in Thunderbird's quick filter bar to use Boolean filters (like AND, OR, NOT)?
I would like to be able to (for example) search on emails send by either Joe OR Jane. See below for an example, which obviously doesn't work.
Note: I don't want to use the "search all messages" options (wonky, slow interface) or "Saved Searches" feature (too cumbersome for one-off searches). So there is no point in suggestion these as a workaround.
Note 2: This is kind of a generalization of my earlier question " Inverse Thunderbird's Quick filter selection? ".
