'body' is not an option on the version of Thunderbird that I have currently. Here is a screen shot. (There also seems to be a corruption bug in kgrab, so sorry for the fuzziness).
** Attachment added: "search pulldown menu" https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1094927/+attachment/3473312/+files/snapshot2.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1094927 Title: Thunderbird cannot search message body Status in “thunderbird” package in Ubuntu: Incomplete Bug description: ctrl-shift-F brings up a search dialog. Many message header fields are available, but there is no option to choose message body. In that way it is not possible to search message bodies for content. What should happen is that there should be an option to search message bodies.
