Search Box Search As You Type not returning anything
I've enabled Search as you Type with a delay of 500 ms (the default). However, no results are showing when typing and waiting. There doesn't appear to be any network activity and there are no JS errors showing.
If I hit enter, it will bring me to the right search page with the right search, so that's working correctly. Any ideas why no results are showing while I'm typing?
"when I try to add the Coveo Omnibox Result List component, I get an "Object reference not set to an instance of an object" " -> Answer: This is a known issue with Coveo for Sitecore 4.0 (171). It should be fixed in June.
"Search as you Type enabled does not work" -> Do you set this option from within the Coveo Search Box View? If so, it is normal that it does not work. Enabling this option in a CoveoSearchbox component would redirect you as soon as you would start typing in the box. This is why the option does not appear in the .cshtml file.
For this issue, are you also using Coveo for Sitecore 4.0 (free edition) and Sitecore 8.1 Update-2?
Search as you type option is meant to be used with a result list. So when you type, it refreshes the result list. With your description, I guess you are working with a "Coveo Search Box" component. This component has a placeholder just under the search box. You can add a "Coveo Omnibox Result List" inside it. Be sure to also use the "Coveo Search Resources" component instead of the "Coveo Search Box Resources" component. The second one is only the minimum resources to display the search box without any suggestions.
I hope this helps.
