@Kinchtwck Full text search is easiest with Latin characters only. Adding Unicode is good but gets much more complicated... I do believe Solr supports Chinese characters and can be installed on the same server as the forum...?
Any plugin out there can generate badge like DN?
There is this plugin: https://github.com/psychobunny/nodebb-plugin-badges
But, I think @psychobunny stopped developing it a while ago, so it probably isn't compatible.
Thanks a lot!
