It doesn't seem clear how offset is counted on command like

    notmuch search --output=files --offset=10 ...

Does it skip 10 output files (which may belong to less than 10 messages)
or does it skip 10 messages (so it possibly skips more than 10 files)?
Manual page speaks of "results" but I think it can be interpreted either
as "displayed output results" or "search match results (messages)".

Perhaps the manual page needs a few more words to make it clear.
