A Pinyin analysis plugin for Elasticsearch, OpenSearch, and Easysearch that converts between Chinese characters and Pinyin. It provides a pinyin analyzer, tokenizer, and token filter with configurable options like first-letter extraction, joined full pinyin, and non-Chinese token handling.

Use cases

• index Chinese names so users can search them by pinyin like 'liudehua'
• enable first-letter search such as typing 'ldh' to match 刘德华
• add pinyin autocomplete or suggestion fields to a Chinese search engine
• tokenize mixed Chinese-English content for full-text search
• build Chinese e-commerce or document search with pinyin matching

When to choose

• you run Elasticsearch, OpenSearch, or Easysearch and need Chinese-to-pinyin text analysis
• you want configurable pinyin tokenization (first letters, full pinyin, joined pinyin) at index time
• your users search Chinese content using romanized input

When to avoid

• you need pinyin conversion outside the Elasticsearch/OpenSearch ecosystem
• you need runtime translation or pinyin annotation of text rather than search analysis
• your cluster version is not supported by the plugin's release matrix
