We built the site with Joomla, Virtuemart, Yootheme Pro and our component VMuikit. In order for visitors to find products quickly, we added an advanced search function at the top of the page.
However, many of the product categories have many different models with different characteristics, which means that just one search cannot help all customers to find the right product. We therefore used a filter function where you can filter a category of properties, price, manufacturers and other fields that may be specific to that category.
