Today we are looking into the Elasticsearch language support of Chinese. Chinese is spoken by the ethnic Chinese majority and many minority ethnic groups in China. About 1.2 billion people (around 16% of the world’s population) speak some form of Chinese as their first language. We are an international company, so having customers in Singapore or Hong Kong makes it super interesting. Chinese consists of many dialects and mostly two written forms. In our first section, I will clarify which region uses what dialect and written form. After that, we are looking at what is supported by Elasticsearch or moreover by Apache Lucene.
