Exclusion activity question

Hello,

I am trying to use an exclusion activity to exclude 1 population from the primary set based on 4 different sets of criteria:

indiv_key

hh_key

email

phone

When taking into account these rules, is the exclusion treating them as "ORs"?  For example, if a record doesn't match on indiv_key but matches on hh_key, will it still be removed or does the record need to match all of the rules?

Thanks!
