I don't think workflows should've been dropped, though.

That's actually treating the entire single-quoted section as
a phrase search for Xapian.

The correct way to use '(', ')', and '*' on the command-line for
Xapian is to shell escape them:

        lei q -I https://lore.kernel.org/all/ -o ~/Mail/floppy \
                --threads --dedupe=mid \
        \( dfn:drivers/block/floppy.c OR dfhh:floppy_\* OR s:floppy \
                OR \(\(nq:bug OR nq:regression\) AND nq:floppy\)\) \
                AND rt:1.month.ago...

Since shell escaping so many metacharacters is annoying,
stdin is supported (and implicit iff file|pipe):

        echo '(dfn:drivers/block/floppy.c OR dfhh:floppy_* OR s:floppy \
                OR ((nq:bug OR nq:regression) AND nq:floppy)) \
                AND rt:1.month.ago..' | \
                lei q -I https://lore.kernel.org/all/ -o ~/Mail/floppy \
                --threads --dedupe=mid
