Hi,

the documentation [1] does mention the Vietnamese analysis plugin:

> **[GitHub - duydo/elasticsearch-analysis-vietnamese: Vietnamese Analysis Plugin...](https://github.com/duydo/elasticsearch-analysis-vietnamese)**
>
> Vietnamese Analysis Plugin for Elasticsearch. Contribute to duydo/elasticsearch-analysis-vietnamese development by creating an account on GitHub.

I already do use the ICU plugin [2] for multi language support.

How much better is the Vietnamese Plugin compared to ICU for Vietnamese language?  
I don't speak Vietnamese, so can't judge.

Does someone has experience with both of them?

tx,  
Jean-Marc

I could answer the question by myself.

There is an example on [GitHub - duydo/elasticsearch-analysis-vietnamese: Vietnamese Analysis Plugin for Elasticsearch](https://github.com/duydo/elasticsearch-analysis-vietnamese)  
"công nghệ thông tin Việt Nam rất phát triển trong những năm gần đây"

It should return:  
["công nghệ", "thông tin", "việt nam", "phát triển", "trong", "năm", "gần đây", "."]

ICU does return: "công", "nghệ", "thông", "tin", "việt", "nam" ...

So the vietnamese analyzer is much better.

Hi Jean-Marc,  
You are right in the above feedback.  
Therefore, we should use the 'specific' analyzer for Vietnamese 🙂  
Cheers,  
Tien
