New-MailboxExportRequest -ContentFilter Received filter issue

I'm trying to search for key words in emails that were received after a certain date. When I run the script below, I get emails with the correct words, but it also exports all the ones from dates prior to what i'm requesting.

Any ideas? 

$username = "User"
$date ="06/01/2015"

((All -like "*Word*") -and (Received -ge $date)) -or ((Attachment -like "*Word*") -and (Received -ge $date)) -or
((All -like "*Word2*") -and (Received -ge $date)) -or ((Attachment -like "*Word2*") -and (Received -ge $date)) -or
((All -like "*Word3") -and (Received -ge $date)) -or ((Attachment -like "*Word3*") -and (Received -ge $date)) -or
