Problem in search product in Opencart admin

Hello

I have problem in my site

I have a product like :

KUCIPA High Quality Earphone

When word Search Quality

Do not leave me any results

But if I wrote

KUCIPA

Get me the results, or if you typed the full name

What bugs here?

This is not bug - default search worked by first symbols of name.

Look on module Autocomplete Plus 2x
This module provide search by part of name (include multiple words or parts), Model, SKU, UPC, EAN, JAN, ISBN, MPN & Location
