The internal search engine shows things wrong

[Andrea_Firenze]

Hi everyone, guys.
I have a problem with the site's internal search engine.

I have a Prestashop. 1.6.1.18.
Since I have migrated from 1.6.1.2 the internal search for the products is wrong.

Before it was much more precise in finding the results. Addition in addition to the article that I want to search, the research shows almost all the products in the category to which the product belongs and not only.

For example:
if I look for "Prexport Boots" in addition to the shoes and boots of the brand Prexport I also find all the products of the brand such as jackets and vests also also finds me other products that have nothing to do with the words typed. It did not happen before.

Another example:
Typing the word "women's jacket", in addition to showing the women's jackets, also shows those for men. This should not happen because in the tags and in the title I was very precise in the difference between man and woman.

Looking on the Forum, I found that someone has solved by deleting and resetting Tags. I have deleted all previous tags and product by product I have recreated them all.

but the problem continues.
Does anyone know how I can fix this annoying problem?

This is just an idea, but I would test this:

Copy classes/Search.php from your old Prestashop version to your current eshop and check if the results display just as before.
