I cloned my dB, then switched on the LocalSettings.php to the new dB, and this resulted in the search stopping to function ("An error has occurred while searching: We could not complete your search due to a temporary problem. Please try again later"). The ElasticSearch service is running OK (I also restarted it) and I can see that the indexes exist. Is there anywhere else that I should change the dB name?
MW 1.31, ElasticSearch 5.6.13
In error log I see:
2024-09-27 10:24:00 host.xxx.gr xxx_1_31_0_bkp: Search backend error during full_text search for 'σαῦρα' after 2: illegal_argument_exception: no mapping found for field [suggest]
