I have upgraded from magento 2.3.5-p1 to magento 2.4.4.

Magento is successfully upgraded to version 2.4.4

But I have noticed issue in advance search.

With Magento 2.3.5-p1. mysql search engine give me result differnet and with magento 2.4.4, elastic search give me numbers of product different count.

For example, with magento 2.3.5-p1, mysql give 11 result on advance search.
