This isn't a true DASL filter, so you end up having to use ranges, in a sense. Unfortunately, you can't use Contains, DoesNotContain, etc. from the filter object reference, as you would with the Search objects. It's a little different.
The following will help you find a range of subjects all between 'test' and 'tz':
use strict;
use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft Outlook';
$|++;
$Win32::OLE::Warn = 3;
my $OL = Win32::OLE->GetActiveObject('Outlook.Application')
|| Win32::OLE->new('Outlook.Application', 'Quit');
my $NameSpace = $OL->GetNameSpace("MAPI");
my $Folder = $NameSpace->GetDefaultFolder(olFolderInbox);
my $Items = $Folder->{Items};
my $findtext = '[Subject] > "test" and [Subject] < "tz"';
my $MailItems = $Items->Find($findtext);
while (1) {
print $MailItems->{Subject} ."\n";
$MailItems = $Items->FindNext() || last;
}
And one should note the following (from the Outlook VB Reference):
Comparison operators allowed within the filter expression include >,<,
+<=, >=,= and <>.
Logical operators allowed are And Not and Or
Update: Slight modification to search string and Text from Find Object Reference.
