Description

Defines a kind of DataFilter.Filter which applies to the extended compound filters. It supports a combination of multiple filter definitions with "$and" or "$or" operator. See ExtendedCompoundFilterDef for additional details and examples.

ExtendedCompoundFilter supports all filter patterns that CompoundFilter supports, Additionally, ExtendedCompoundFilter also supports NestedFilterDef and TextFilterDef filter definitions which CompoundFilter does not support. While CompoundFilter can be used for backward compatibility reasons, ExtendedCompoundFilterDef should be used in place of CompoundFilterDef going forward.
