We have 4 products with the name:
1.Смартфон SAMSUNG Galaxy S20 черный
2.Смартфон SAMSUNG Galaxy S20 серый
3.Смартфон SAMSUNG Galaxy S20 красный
4.Смартфон SAMSUNG Galaxy S20 серый космос
• we have a synonym "черный => серый космос"
upon request SELECT * FROM products WHERE search_products = '@name +samsung +galaxy' I get all 4 items.
upon request SELECT * FROM products WHERE search_products = '@name +samsung +galaxy +серый' I get 2 items:
2.Смартфон SAMSUNG Galaxy S20 серый
4.Смартфон SAMSUNG Galaxy S20 серый космос
upon request SELECT * FROM products WHERE search_products = '@name +samsung +galaxy +серый +космос' I get item:
4.Смартфон SAMSUNG Galaxy S20 серый космос
But if I add word required "черный", there will be errors:
SELECT * COUNT() FROM products WHERE search_products ='@name +samsung +galaxy +черный'
I expect to get two products, but I get three:
4."Смартфон SAMSUNG Galaxy S20 серый космос"
1."Смартфон SAMSUNG Galaxy S20 черный"
and excess product 2. "Смартфон SAMSUNG Galaxy S20 серый"
