New filters improve shopping search while laying the foundation for thousands of product attributes and sortable specifications

ST. LOUIS, Sept. 2, 2026 /PRNewswire/ — Hot Sphinx today announced the completion of Phase One of its advanced product discovery rollout at HotSphinx.com. Shoppers can filter results by seller, brand, price range and whether a listing includes an image, while pagination makes deeper result sets easier to explore. Consumers can try the new features at HotSphinx.com.

Key Highlights

• Filter by seller, brand, price range and image availability
• Explore deeper result sets with pagination
• The majority of requests complete in under 100 milliseconds from request through response to rendered page
• Phase Two will add thousands of searchable product attributes and facets
• Hundreds of sortable numeric specifications are planned for the next phase

The release is the first live step in the advanced product discovery platform Hot Sphinx announced earlier this year. Shoppers are already using the filters to narrow broad searches to niche products from brands and sellers within preferred price ranges.

“Intersecting millions of products across all of their different product attributes is a steep technical undertaking,” said a spokesperson for Hot Sphinx. “Implemented poorly, filtering and sorting can bring search to a crawl. Traditional algorithms proved too slow and too generic for our needs, so we built our filtering, ranking and sorting algorithms from the ground up for today’s modern hardware.”

That approach allows Hot Sphinx to add discovery tools without sacrificing speed. The majority of requests complete in less than 100 milliseconds for the full round trip, measured from request through response to rendered page.

The image filter lets shoppers distinguish between listing formats. Organic Hot Sphinx results appear as text links, while enhanced listings from sponsored sellers can include product images. Sponsorship does not determine organic search relevance.

Phase One establishes the foundation for a deeper second phase. Hot Sphinx has developed technology that identifies product characteristics across a large portion of its catalog, creating thousands of searchable attributes and facets plus hundreds of numeric specifications.

“We wanted shoppers to experience the benefit with filters they already understand before we open up the much larger attribute set,” the spokesperson said. “Once someone sees how quickly a broad search can become a very specific set of products, the value of filtering by detailed product characteristics becomes immediately clear.”

Phase Two will expand discovery into category-specific characteristics such as dimensions, capacities, quantities, materials, technical specifications and performance attributes. The goal is to help shoppers find products based not only on listing keywords, but on the characteristics that matter to the purchase.
