Fibosearch index

Hello, I have written two emails from the support through the web with no response.

I have two problems:
1. The indexer gives an error:

2022-08-30T12:50:13+00:00 EMERGENCY [30652] [Variation index] Database error "Error en la base de datos de WordPress: Ha fallado el procesamiento del valor del siguiente campo: sku. El valor facilitado puede ser demasiado largo o contener datos no válidos." | Type: 0 | File: /home/hostelshopespana/www/wp-content/plugins/ajax-search-for-woocommerce-premium/includes/Engines/TNTSearchMySQL/Indexer/WPDB.php | Trace: #0 /home/hostelshopespana/www/wp-content/plugins/ajax-search-for-woocommerce-premium/includes/Engines/TNTSearchMySQL/Indexer/Variation/Indexer.php(114): DgoraWcas\Engines\TNTSearchMySQL\Indexer\WPDB::insert('wp_dgwt_wcas_va...', Array, Array)

– I’ve inserted this and it still doesn’t work:define(‘DGWT_WCAS_INDEXER_MODE’, ‘sync’); to your wp-config.php

2. I don’t want a category to appear in the search bar, what do I have to do?

Thanks for your help ??
