E-commerce faceted search

Fast, accurate, and personalized results

Faceted search is a state-of-the-art technology that can help website visitors find the most relevant results based on the entered query and narrow it down thanks to multiple relevant facet options.

For example, suppose your visitors search for “laptop”. In that case, the search will show multiple filter options such as “ultrabooks,” “MacBook,” or “Microsoft Surface” to help them narrow down the search and guide them to the exact product category they want to browse.

Customizable dynamic facets

Easier navigation with always-relevant filters

Luigi’s Box search will show only relevant, thematic filters that match the product type, so there will be no redundant filtering options to confuse your visitors.

The search facets are also customizable, which means that you can help visitors even further by adjusting the options and helping them narrow the search with the most relevant product categories. This feature is also useful for helping you guide your visitors to the categories you want to show first.
