There is an issue where a QnA answer is not retrieved although the user phrase matches the question phrase exactly.

solved by increasing the "Top" parameter to 120 when calling the prediction API. This is caused by the large size of the knowledgebase.

Thanks for sharing this. I am a little bit confused about the solution. Could you please tell which "Top" parameter you are mentioning?

It's a parameter in the POST request body to the generateAnswer API

Example post body to generateAnswer
{
"question": "What do you do?",
"top": 120
}

You will still see the error on the QnAMaker portal test window. However, this will solve it on your bot.
