I have a data field that I want Elastic to ignore. It has things elastic does not like: Mixed type arrays, tons of fields (since ID is a key), etc. It is valid JSON, but I am not wanting to index that field, it is raw, and I cannot figure out how to set it raw and have Elastic ignore it. ?? I just want it in the _source and tagging along with the other fields which are indexed.
I did set index=false. But Elastic still maps it, and it complains number of fields > 1000, and ignoring field update, etc.
Is there a concept of a raw, or external field?
