For example, setting the criteria to find matches for a blood pressure with a diastolic greater than 120.

If you right click, select Options and change to Exclude leaving the tick next to Exclude patients with no records for this entity, then the search finds patients who do not have a blood pressure over 120, and also excludes any patients without a blood pressure recorded.
