product sku work - only without dot

[tommy83]

Magento 2.2.3
php 7.1

Search will not find product if dot is included
product sku: 145.6
Search product by: 145.6
Product will be not found.

product sku: 1457
search product by: 1457
Product will be found.

The extension will not find product by sku if sku have a dot (.).
In magento standard search it's working with and without dot.

How to fix this issue?
