To bulk update synonyms for your index via the Magento Admin, go to Configuration > Synonyms and upload a JSON file in the "Synonyms file" field. The JSON file should adhere to the specifications outlined in this documentation.
Note that unlike the Algolia dashboard, you cannot upload a CSV file in the Magento Admin.
As displayed in the Magento Admin, uploading a JSON file in the "Synonyms file" field will override any values manually entered in the "Synonyms" and "One-way synonyms" fields.
