• property — Specifies properties of interest

• excludeProperty — Specifies properties to be excluded

• expandProperty — Specifies a property to be selected and, if that property is an array, specifies that each value in the array should be selected

• first — Specifies a number of values at the beginning of an array that are to be selected

• unique — Specifies that only unique values are to be selected

• inputObject — Specifies an input object, if the input objects are not supplied by the preceding step of a pipeline
