BotBuilder-CognitiveServices | Microsoft Cognitive Services controls for Microsoft Bot | Bot library

My FAQ bot is using this QnAMakerDialog which is not using Microsoft.Bot.Builder.CognitiveServices.QnAMaker, but easy to use metadatas.

However I also want to train[CustomFeedBack, ActiveLearning] like these samples which is using Microsoft.Bot.Builder.CognitiveServices.QnAMaker.

Microsoft.Bot.Builder.CognitiveServices.QnAMaker provides method like QnAFeedbackStepAsync.

Q1: Does QnAMakerDialog which is not using Microsoft.Bot.Builder.CognitiveServices.QnAMaker have some similar methods like QnAFeedbackStepAsync ?

Q2: How to use metadata while using Microsoft.Bot.Builder.CognitiveServices.QnAMaker ?

Q3: QnA Maker REST API V4.0 don't support to use train knowledgebases. Although my bot is using V3.0, is it better not to use train knowledgebases?

I am using LUIS for azure search and QnA recognizer for the first time together in the same code.

I am using intent.match to match the recognizers.

My problem is:

for the first time, If I ask a question which matches to the QnA intent, it returns the answer from the QnA base.

followed by the questions which are matching with the azuresearch intents. Azure search also deliver the result.

But if I repeat the questions which must be matched to the QnA, it says "no intent handler found for null"

I am making a chat bot using the QnA template (Microsoft Azure). Basically, a user asks a question and the bot will try and find the answer in an FAQ document. If it fails, I want it to run a Bing search with the user's query and replies with the most accurate answer. I found this example that uses Bing Web Search API: https://docs.microsoft.com/en-us/azure/cognitive-services/bing-web-search/quickstarts/nodejs. For now, I just want the bot to reply with the first link of the search for example. However, I don't know how to merge the code in the link, with the generated code for the QnA Bot (in Node.js):

Once the bot is created using qnamaker.ai, I wanted to deploy it in Azure using the SDK and publishing from VS2017, which let me define the top parameter to enable the Active Learning as shown in https://github.com/Microsoft/BotBuilder-CognitiveServices/tree/master/CSharp/Samples/QnAMaker But when I want to register it in dev.botframework the end point URL doesn't work.

If I use Azure Bot Service template, is not possible to set the top parameter but registering in my Bots is ready straight forward. I have realized that the URL from Azure template contains some extra info, that is not available in my web app ...code=2xDGuyPbupZIm8zsDOucgcHDvXO908dPIad2LFG2y/37TPecdMfQEw==

A "typical" URL from Azure, that work with other deployed Bots is https://"MyBotName".azurewebsites.net/api/messages

Please, can you help enabling the active learning in Azure templates for a Q&A bot? Can you explain me what should I add to get the "extra details" in my Web app URL?
