well, aggregations are just leveraging how the data fields are analyzed and labeled, so if those were based on ML/NLP techniques then it could be legit

Occam's Razor is whispering that it probably wasn't legit.
i believe the only NLP/ML stuff we really had was at the level of positive / negative sentiment analysis for social media posts, which as far as i know is pretty basic and mostly just involves dictionary checks for +/- words. the elasticsearch aggregations & indexing was not ML/NLP based at all.
