What it does
This class handles attribute-based filtering in Magento 2 catalog search and layered navigation.
Developers use it to filter product collections by attribute values (like color, size, material) and display available filter options with product counts.
It processes filter requests from the frontend, applies them to search results, and builds the filter option data displayed in the sidebar.
