Content autosuggest is not working in coveo for sitecore.
Content autosuggest is not working in coveo for sitecore. @fields & fields suggestions are working but we need autosuggest on content instead of content fields. In advance omnibox suggestions i checked "Enable suggestions of query extensions" option & rest two options remains unchecked ("Enable field suggestions after typing @ in searchbox","Enable field suggestions in searchbox").
Can any one please suggest why autosuggest is not working in my case?
Answer to your Question 1:
The option "Enable suggestions of query extensions" will suggest Coveo query extensions : https://developers.coveo.com/display/public/SearchREST/Standard+Query+Extensions
For example, if you type ''$", you should get "$qre" as a suggestion for example.
Answer to your question 2: "can any one please suggest why autosuggest is not working in my case"
