But my centmin based Xenforo cannot. What could be the cause?
Xenforo 1.5 or 2.x ? Can you do chinese search on my forums ? I am using Xenforo Enhanced search via Elasticsearch and I believe official Xenforo forum is too.
Yes I posted a thread in the test forum. No problem with Chinese searching, title and inline. The same for official website. I'm using centmin, Xenforo Enhanced search via Elasticsearch too. Anything need to be changed in the DB settings?
Have you asked on Xenforo support forums ? Might depend on character set and collation of your MariaDB server and Xenforo database/tables. For my forums on XF 1.5 I am using UTF8. I believe Xenforo.com on XF 2.1 switched to UTF8MB4 for emoji support. Centmin Mod 123.09beta01 defaults to UTF8 too for MariaDB 10.3 installs. Character set collation for MariaDB server can be checked as per MariaDB MySQL - CentminMod.com LEMP Nginx web stack for CentOS via SSH command Code (Text): mysqladmin var | grep -E 'character|collation' | tr -s ' ' which gives me Code (Text): mysqladmin var | grep -E 'character|collation' | tr -s ' ' | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | | collation_connection | utf8_general_ci | | collation_database | utf8_general_ci | | collation_server | utf8_general_ci | | session_track_system_variables | autocommit,character_set_client,character_set_connection,character_set_results,time_zone |
