Learning process

CODE LEARNING RECORDER

Why start this? The answer is to record the technology that I had learned after 2023.6.19.

- 2023.6.19

es：use DSL to complete data aggregation（bucket、metrics）
es：use RestAPI to complete data aggregation（bucket、metrics）
es：heima project:implement bucket aggregation in the project
es：Learn about auto-completion techniques:pinyin

- 2023.6.20

combination of tokenizers&custom design tokenizer（DSL）

- 2023.6.21

Auto-completion (DSL)
