When a user asks several questions at once or enters a long text, it is usually to approach complex topics with subtleties that a simple sentence could not sum up. In this case, the chatbot will only react to a few keywords and there is therefore very little chance that the AI will give a relevant response. It is better to turn off the AI for this specific case and offer the user other means of obtaining a response such as putting them in contact with a human operator via live chat, by phone or by leaving a message. This temporary deactivation will only be triggered in this case and will reactivate immediately afterwards automatically.
In the advanced settings of your chatbot, there is an option "Disable AI". It is this feature that allows the user to be referred to a particular sequence when they have entered too long a text. You can determine the number of characters beyond which this feature is triggered.
