5. Complex queries
A complex query is a parameter query that searches using more than one parameter value i.e. on two or more criteria.
It might be an AND query. The example below shows that the query is searching for event = birthday AND paid = yes
It might be searching using two parameters for event = lunch OR event = birthday
The parameters might be looking for all events except for birthday.
