Channel Setting: Show Search Advice in Empty Search Text
Goal: When your users will search for something they may expect fuzziness or corrections, which are not yet available to the full degree. Therefore you can help them by displaying a note which explains the correct syntax, as not all users may be fully familiar with ES Query Syntax.

Make yourself familiar with search analyzers to improve the search experience. Especially n-gram and edge n-gram analyzers can produce single tokens which may result in results when users misspell the search term.

Your search terms couldn't find anything. You can try searching with fuzziness.
The number you add is the level of fuzziness e.g. ~4 means up to 4 characters can be mixed up.
Try this in advanced search mode: {{response.searchString | append:"~4"}}
