CJK Tokenizer
This module is to provide a better and faster search experience for languages ​​
such as Chinese, Japanese and Korean. For languages ​​in Asia countries, Drupal's default
implementation is too simple, it will cause problems such as waste of storage and slow
down the system. It is especially prominent for sites with a large amount of content. The
reason is that the default words tokenization algorithm ​​is designed to deal with
latin languages like English or German.
