Before this rev.,
if you had two child categories with the same name, e.g.:
- Chocolates / Orange
- Fruits / Orange
In the product list, searching for category "Fruits / Orange"
also returned the products from category "Chocolates / Orange",
because it fetched all products which had "Orange" in the category.
This rev. corrects this (in the above example, it returns
only products from category "Fruits / Orange".
The code is particularly complex. A proper solution would be
to store the complete name field (but this cannot be done in
stable releases, such as 8.0).
Besides, it handles the fact a product category child can have
' / ' directly in its name (it's not only the category tree separator).
e.g., you could have a category name called 'Fruits / Orange' directly
not only in the complete name.
