Name	Overview
complement	Returns the distinct values from the specified array that do not appear in the pipeline input, preserving the specified array order. Returns null when the input cannot be evaluated.
difference	Returns the distinct values from the pipeline input that do not appear in the specified array, preserving the pipeline input order. Returns null when the input cannot be evaluated.
distinct	Returns the unique values from the input array in the order of their first occurrence. Returns null when the input cannot be evaluated.
intersection	Returns the distinct values found in both the pipeline input and the specified array, preserving the pipeline input order. Returns null when the input cannot be evaluated.
symmetric-difference	Returns the distinct values that appear in exactly one of the two arrays, listing pipeline-input exclusives first and parameter-array exclusives second while preserving order within each source. Returns null when the input cannot be evaluated.
union	Returns the distinct values appearing in either the pipeline input or the specified array, listing pipeline-input values first and argument-only values second while preserving order within each source. Returns null when the input cannot be evaluated.
