You can define expressions to filter PowerDesigner lists directly in the list with the in-column filters or through the Customize Columns and Filter dialog.
The following operators are available

                        "global", "Architecture", "proc*"  |

                             Located in the range between defined by the two values given in the expression and separated by a comma. For example, to find values between A and E, enter: 
                        A,E  |
