redact

public Aggregator<T,R> redact(Expr redact)

redact needs to resolve to $$DESCEND, $$PRUNE, or $$KEEP

System Variable Description $$DESCEND $redact returns the fields at the current document level, excluding embedded documents. To include embedded documents and embedded documents within arrays, apply the $cond expression to the embedded documents to determine access for these embedded documents. $$PRUNE $redact excludes all fields at this current document/embedded document level, without further inspection of any of the excluded fields. This applies even if the excluded field contains embedded documents that may have different access levels. $$KEEP $redact returns or keeps all fields at this current document/embedded document level, without further inspection of the fields at this level. This applies even if the included field contains embedded documents that may have different access levels.
