search for attachments AND size is not working

[Olifair]

when searching for "attachment: yes" or "a: yes" then I get 561 results, however if I do "a: yes larger: 100" I get only 1 result, even though I know that there are several hundred emails with size > 500kb. When I search for only "larger: 100" I get 12 results. Is there anything wrong in my setup ? Thanks in advance for any help

I have the same result when using version 1.4beta : I only get 12 results for larger: 100 and none of the emails foudn has actually an attachment
