- **Messages with/without attachments** - By default, all messages are searched, regardless of whether or not they have any file attachments. Clear one of the check boxes to remove certain emails, such as those without attachments, from the results.
- **Important:** These searches can be imprecise at times because items like background pictures could be regarded as attachments.
- **Size** - By default, all messages are searched regardless of their size. Use the appropriate fields provided to limit the search according to the size of the emails, e.g. at least *5 MB* or between *400 and 600 KB*.
- **Priority** - Emails are searched according to the priority level of the email as assigned by the sender. When choosing*Low*, all emails with a priority level lower than *Normal* are returned, when choosing High, all emails with a priority level higher than *Normal are returned*. Emails not containing any information regarding priority are assumed to have a priority level of *Normal*.
