Could you provide a full recreation script as described in > [@About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21): > > The heart of the free and open Elastic Stack Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a growing number of use cases.

1. Create a simple index and mapping, the mapping use default analyzer. 2. Index some records with Chinese words. 3. Using java client build a match query, operator is 'and', value are Chinese words. 4. Then java client execute the query, the result hit nothing(There are really have the words in the index). 5.The java client tostring method will print the query , in which the Chinese words are converted to \uxxxx 5. If I paste the printed json string in the head plugin, then search, aslo hit nothing. 7 but if i change the converted Chinese words from \uxxxx to real Chinese, the head query will hit. ---

I understood what you do. I just need a script I can play to reproduce it. ---

It's my fault. Thx you very much. I use the apache common lang StringEscapeUtils to escape special char, which will convert Chinese to \uxxxxx. How to escape the {} ! chars? ---
