Fetch Unopened Emails

I need a way to fetch customers who were sent an email campaign but did not open it. Currently, you can fetch all customers who received an email from a specific campaign using:

source = contact history and then REASON IS LIKE "CAMPAIGN NAME and "Contact Type" LIKE Marketing

You can also fetch those who have opened a specific campaign by using:

REASON IS LIKE "CAMPAIGN NAME - JANGO MAIL - OPEN"

However, there is no way to return these combined results since they are 2 unique contact history entries.
