Prestashop 1.7.4.2 - How to change the search auto complete keyword length

Prestashop 1.7.4.2 auto-complete search feature is very handy especially when you have a large database of products - allows the users to search the item quickly as suggested by the keywords that exist in the DB. It is one of the most important features that speed up the customers' intention to look through the product list in the store.

However, the default auto-suggested keywords are set to 3 characters - which means it requires the visitors to type at least 3 words in order for the suggestion to pops up. We can make that more flexible by changing it to 1 character so it is very easy to give an idea to the potential buyers what available in the store.
