Evolution fails to see some messages in Inbox

[Jonathan Ryshpan <jonrysh pacbell net>]

I see no messages displayed in Inbox earlier than Sept 11, 2007, though
I know there are earlier ones.  If I search Inbox for a message that I
know is there, received in 2005, it's not found.  But if I search the
*Account*, rather than Inbox, for the same message it is found.  

Can anyone explain this?

Inbox is rather large:
	3032 unread 8014 total
