Answer 1

Analysis, filter, analyzer, plus Chinese word segmentation and pinyin, this is already a huge amount of knowledge.
Why don’t you start from the manual? Although I have just come into contact with elastic, I have spent a lot of time studying the manual.
After all, this thing is huge and not so easy to get started

Chinese manual (version 2.x): http://es.xiaoleilu.com
Official manual: https://www.elastic.co/guide/...

After reading the Chinese manual, I slowly started to read the official manual, and gradually gained some understanding of the above analyzers.
