Flag filter

A flag field is a database field the values of which can only be either true or false. A flag filter allows you to match against one of several pre-defined flag fields. To add a flag filter condition, select the Flag Filter radio button option. Each flag filter has two parts: the flag field on which you filter, and an operator that controls the behaviour of the filter with respect to your selected flag field.

You can set the flag field from the drop down list. Set the flag field to Is Recommended to match against recommended crudes, or to Is User to match against user crudes.

To control the behaviour of the filter, use the Is Set and Is Not Set radio button options. When the option Is Set is chosen, all crudes having the value true for the selected flag field will be matched. When the option Is Not Set is selected, all crudes having the value false for the selected flag field will be matched. Thus, for example, a flag filter condition of "When flag is recommended is set" will match all recommended crudes in the database.
