I am having issues getting Autosuggestions to work on the hosted UI configuration in Custom Search - https://docs.microsoft.com/en-us/azure/cognitive-services/bing-custom-search/hosted-ui Inside Azure Cognitive service you’ll see I have all settings configured i.e both a Search and Autosuggest service. Both of these are on a paid tier. Enable autosuggest is enabled in the Hosted UI page. In http://customsearch.ai/ in the Hosted UI page there are options to configure the search keys: For the search service the API key appears However, for Autosuggest it doesn’t. I can manually type the API key in from the service but that doesn’t see to help. I have checked all the docs and done search but can’t get Auto suggest working in my custom instance at http://bit/ly/ciasearch. Do you know anyone that can help?
