This question has been asked before:
Postgresql full text search in postgresql - japanese, chinese, arabic
but there are no answers for Chinese as far as I can see. I took a look at the OpenOffice wiki, and it doesn't have a dictionary for Chinese.
Edit: As we are already successfully using PG's internal FTS engine for English documents, we don't want to move to an external indexing engine. Basically, what I'm looking for is a Chinese FTS configuration, including parser and dictionaries for Simplified Chinese (Mandarin).

When performing a full-text searches on a PostgreSQL database, you must implement the to_tsvector() and to_tsquery() functions together with a match operator @@. The match operator returns a boolean value (either t or f) when you run a keyword search (tsquery) against a tsvector document.
Yes, You Can Keep Full-Text Search in Postgres You can get even deeper and make your Postgres full-text search even more robust, by implementing features such as highlighting results, or writing your own custom dictionaries or functions.
To summarize, we learnt how to perform full-text search operation in PostgreSQL. If you liked our article, check out the book Mastering PostgreSQL 10 to understand how to perform operations such as indexing, query optimization, concurrent transactions, table partitioning, server tuning, and more.
PostgreSQL Full Text Search refers to a technique in which you search for a single computer-stored document or a collection in your full-text database. It provides you with the capability to identify natural languages documents that satisfy a query.
I know it's an old question but there's a Postgres extension for Chinese: https://github.com/amutu/zhparser/
