You can directly use search as follows:

[~] grep ^Subject Mail/linux-kernel/321805

pick: no messages match specification
scan: no messages match specification
There's still something busticated here. Why did it match even with the Re: in
there?
A modified grep(1) is used to perform the matching, so the full
regular expression
(see ed(1)) facility is available within pattern. With -search,
pattern is used
directly, and with the others, the grep pattern constructed is:
`component[ \t]*:.*pattern'
I understand why that .* was causing me indigestion. But I'm having a hard
time matching "pattern is used directly" with what I'm seeing, unless -search
is *also* doing a split into component and pattern and constructing a grep
expression from the two that includes the .* implicitly?
Also, saw this under 'BUG' in the pick manpage:
The pattern syntax '[l-r]' is not supported; each letter to be matched must be
included within the square brackets.
However, '[45].[0-9]' matches 4.14 and 5.1 quite nicely.
