What they do?
Their work starts long before a customer types a query. They’ve been analyzing data, observing past traffic patterns, and indexing the text describing every product in their catalog before the customer has even decided to search. As soon as they see the first keystroke, they’re ready with instant suggestions and a comprehensive set of search results.
How it works?
One of A9’s tenets is that relevance is in the eye of the customer and they strive to get the best results for our users. Once they determine which items are good matches to the customer’s query, their ranking algorithms score them to present the most relevant results to the user.
Their ranking algorithms automatically learn to combine multiple relevance features. Thier catalog’s structured data provides us with many such relevance features and we learn from past search patterns and adapt to what is important to our customers.
