I want to use aggregations over the search result of the knn_search api in elasticsearch (because I need facet search on the user interface), but I cannot pass the agg parameter as in the search api. Any suggestions?

Tldr;
As per the documentation of this endpoint GET /<index>/_knn_search.
You just can not give the parameter agg.

Although in the latest version of elasticsearch, you can use the knn search in the standard search queries.
