A filter is a program or section of code that is designed to examine each input or output request for certain qualifying criteria and then process or forward it accordingly.
...
In filter field, we are using two Main Operators:
(1) AND:
The logical AND operator is an operator that performs a logical conjunction on two statements. It only yields a value of "true" when both statements are true. If one of the two statements is false, then the logical AND operator yields a "false" value.
...
The OR operator is a Boolean operator which would return the value TRUE or Boolean value of 1 if either or both of the operands are TRUE or have Boolean value of 1.
Filter Fields:
Filter Field will map the variable to the actual column data. The filter widget connected to the variable then knows which categories are available, and can present a drop down menu of those categories.
Filter Operators:
Equals:
