Defining criteria expressions

This section describes the ways in which you can enter criteria expressions to select records; outlines how the expressions are evaluated and processed within File Manager and provides a list of operators and functions that can be used in criteria expressions.

To specify record identification or record selection criteria, you can enter a freeform expression into a relevant field or you can build the expression “by field”. These methods are mutually exclusive. If you create a freeform expression and then create an expression by field, your freeform expression is overwritten. Once you have specified an expression by field, you cannot enter a free form expression until you delete the “by field” expression from the relevant panel.
