Typeahead parameter

Hello, i have deployed map web SDK on my machine, using search with autocomplete, as mentioned in the document that if typeahead parameter is set the query will be interpreted as a partial input, and the search will enter predictive mode. But if its false then ? user will not have suggestion against whatsoever they type ?? i’m trying to develop an understanding here that how search (fuzzy search) and autocomplete relate ? If we search in maps and go to inspect element, there’s a parameter of “typeahead” which is set as true. but if set it as false or remove it from “search with autocomplete” file then my changes doesnt reflect but somehow limit changes reflect.
