You cannot use FT.CONFIG SET to configure RediSearch in Redis Enterprise Software or Redis Cloud. Instead, use one of the following methods.

For Redis Cloud:

  • Flexible or Annual subscriptions: contact support to request a configuration change.

  • Free or Fixed subscriptions: you cannot change RediSearch configuration.

For Redis Enterprise Software, use either:

  • rladmin tune db:

    $ rladmin tune db db:<ID|name> module_name search \
        module_config_params "setting-name setting-value"
    
  • Configure module REST API request:

    POST /v1/modules/config/bdb/<ID>
    {
      "modules": [
        {
          "module_name": "search",
          "module_args": "setting-name setting-value"
        }
      ]
    }
