Since 2.4.7 we noticed search autocomplete would suggest search terms with no result.

here are some more cases of bad search suggestions with sample data package : Intending to search for "Didi Sports Watch" "didi" -> suggestion "duti" with no matches

Intending to search for "Bottle" "bot" -> suggestion for "but" and "boi", the latter bringing no search results

Intending to serach for "Summit "summ" -> suggestion "seam" and "sued" which bring results but not the watch Manual testing scenarios (*)

install sample data package
type in following terms in searchbox on store front and verify it don't suggest autocomplete with strange result:

"didi" -> does not suggestion "duti"
"bot" -> does not suggest "boi"
"summ" -> does notsuggestion "seam" or "sued"
