The field you are trying to store the data is most likely defined as "type" : "keyword". "keyword" should only be used for exact match lookups (think "category") and thus indeed has an upper limit: https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html But storing such a huge amount of text into a "keyword" field makes no sense. So the proper fix is to index that data into a field that's defined as "type":"text". (Only then can you do partial matches on the content!) If this is not possible, you can tell ES itself to cut off the text using `ignore_above`: https://www.elastic.co/guide/en/elasticsearch/reference/current/ignore-above... So instead of handling this via code as suggested in the patch it should be handled via fixing the ElasticSearch mappings for this (and maybe other) fields. I've taken a quick look at `elasticsearch/mappings.yaml` but did not find any indicator there that 500 should be used as a keyword. BUT: I do not really understand how your solution can fix the issue, so maybe all I'm saying now is wrong... I can try your bug later (not sure if during the weekend) to get a better understanding Greetings domm -- You are receiving this mail because: You are the assignee for the bug.
