in the configuration file (standalone.yml/data.yml). I can guees what it means through its name. The issue is that my locale is CN-zh or my main language is Chinese (That means the same, lol ) and my setting is the default (pg_catalog.english, never noticed), and my pg text search work just well. So what does that do? I can find nothing useful in this site.
So, what if i change this setting to db_default_text_search_config: "pg_catalog.chinese" or db_default_text_search_config: "pg_catalog.simple". What will happened?
