Introduction

Typeahead suggestion or autocomplete feature enables users to search for a known and frequently searched query. When a user types a query in the search box, this feature comes into play. The typeahead provides a list of suggestions to complete a query based on the user’s search history, the current context of the search and trending content across users or regions.

It is an essential part of all search engines which assist in enhancing the user experience.
