pkg/util/json/json.go:1077–1083

EncodeContainingInvertedIndexSpans takes in a key prefix and returns the spans that must be scanned in the inverted index to evaluate a contains (@>) predicate with the given JSON (i.e., find the objects in the index that contain the given JSON). The spans are returned in an inverted.SpanExpression

(
	b []byte, json JSON,
