That is correct. That ruby filter only checks the top-level fields. [This](https://discuss.elastic.co/t/how-to-exclude-xml-json-key-value-if-key-length-is-greater-than-15-char-and-value-length-is-greater-than-100-char/270248/8) is an example of ruby code that recursively descends into fields of an event and modifies them.
