Such question is asked by newbie.  But, since you're asking this, there
must be something else to it.  Can you give an example?

Header and body are separate section of email message, so they should be
searched separately.  There is no reason why an email message shouldn't
be in memory (ie. procmail does it), so without more detail, it's
difficult to answer.
