Change default answer for custom question answering

The default answer for a project is meant to be returned when an answer is not found. If you are using a client application, such as the Azure AI Bot Service, it may also have a separate default answer, indicating no answer met the score threshold.

Default answer

Default answer	Description of answer
KB answer when no answer is determined	No good match found in KB. - When the custom question answering API finds no matching answer to the question it displays a default text response. In custom question answering, you can set this text in the Settings of your project.

Client application integration

For a client application, such as a bot with the Azure AI Bot Service, you can choose from the following scenarios:

• Use your project's setting
• Use different text in the client application to distinguish when an answer is returned but doesn't meet the score threshold. This text can either be static text stored in code, or can be stored in the client application's settings list.
