To some extent, yes. Though emails are structured text and a bare string search is far from an optimal search strategy.

Whatever the Thunderbird default is.
Thanks and good point about the structured data.
I ask about mbox (one file system file per Thunderbird folder - e.g., one file named Inbox containing all its messages) or maildir (one folder per TB folder, containing one file per message) because it affects search using outside tools that don't understand that folder structure.
I'm wondering how efficient they are: When you search, does grep return an Inbox mbox file at a certain line number, or a maildir file?
