[Evolution] S-Expression keyword to query folder information?

[Sean <shizeon gmail com>]

Hi, 
  Can't seem to find any examples or docs for the keyword to use in an
expression for a search folder to match for certain folders.  I would
like to create an expression that looks only in certain folders
depending on some naming convention.  Is this possible?

Something like:

(match-all (and (header-exists "x-camel-mlist")
                (not (system-flag "Seen"))
                (FOLDER NAME STARTS WITH XXX)))

or

(match-all (and (header-exists "x-camel-mlist")
                (not (system-flag "Seen"))
                (FOLDER NAME IS NOT Inbox/Lists/Archive)))

Thanks for any tips!
