[Evolution] Hidden emails when searching in the whole account

[Simon Siemens <simon siemens arcor de>]

Hi,

I use Evolution for my IMAP account. The inbox there contains several
folders. The inbox almost no email. All are in those folders. 

When I search with the search bar in the whole account, then only a
subset of the hits are shown. In a specific example, only one email is
shown in the results list, whereas the application title say "Konto
durchsuchen (11 insgesamt) - Evolution" (in English, it is something
like "Account search (11 in total) - Evolution"). I did not count the
real number of emails that match the search, but 11 sounds quite
reasonable. The one it shows, is the only match, which is in the inbox.

So, how can I make Evolution show me all eleven hits?

If I go into a folder and search only in it, all emails are shown.

I played a bit with the view menu, with no success though. Hide deleted
messages is marked, but has no effect if I unset it. Actually, the
emails I am looking for, are not deleted. The other options (hide chosen
and read message, show hidden messages) are not marked.

Can you help me how to do searching right in Evolution?

Thanks much and best regards,

Simon
