You can see the WooCommerce official documentation live at https://docs.woocommerce.com/.
WooCommerce docs features a prominent search bar. It has the capability of doing a search refined by various product categories such as themes, plugins or extensions. This might be useful considering the vast array of different products that WC encompasses, but the list also feels a bit bulky.
One drawback of the WC documentation approach we can see in the main page is that there are multiple products represented there. Instead of having complete separation, the WC docs pages also has content for Sensei and other plugins, themes and more. Even though core WC seems to be front and center, the overall impression is one of clutter and poor organization.
