Hello, I am using ingest attachment to search document. The requirement need to handle chinese, so we want to use ik as analyzer for attachment.content.

But for some reason it's not working, I think it's still using default analyzer. Below is the json to create index, add document and query.

Any advice will be appreciated, thanks in advanced.

Please try this setting and use `_analyze` API to test `ik_smart` and `ik_max_word` analyzer
