I looked in:
/usr/share/evolution/vfoldertypes.xml
~/evolution/vfolders.xml
Using a combination of your hints and guesswork, I constructed a simple
vfolder with an expression, and then a more complex one. The detailed
example is:
Rule name: Exp
if all criteria are met
Expression (match-all
(and
(or
(header-contains "From" "Muller")
(header-contains "From" "TomF")
(header-contains "From" "Eric")
)
(or
(header-contains "To" "TomF")
(header-contains "Subject" "boolean")
(header-contains "Subject" "custom")
)
))
Date sent is after 2 days ago
Specific folders only
vfolder:/home/tom/evolution/vfolder#Tom important recent unread
The Exp vfolder displayed all messages from the "Tom important recent
unread" vfolder that were sent after 2 days ago, were from one of TomF,
Eric, or Muller, and were either to TomF, or had boolean or custom in
the subject.
Note that Evolution is weak on syntax checking: my first try at a
complex expression crashed because of a missing parenthesis. I
submitted bug report http://bugzilla.ximian.com/show_bug.cgi?id=46463
Also, the vfolder editor has too little space for an expression, so I
used gedit to build the expression, and pasted it into the vfolder
editor.
