Redefining Auto Trader Search

The problem

Auto Trader is the UK's biggest car sales website. Search is the key piece of functionality and prior to the redevelopment it was very difficult to use and slow. The search works by choosing criteria that would reduce the options for the next criteria. For instance, when choosing the car Make it would filter the Model field. However each filter change would cause a refresh of the entire page.

The Solution

We built a brand a new search system that worked in real time without refreshing the page every time the criteria were altered.

The Technical Bit

Integrating with a brand new REST service we built on top of existing web services we created a javascript search engine that dynamically loaded the various criterion as the user changed their requirements. The results were a a huge success, particularly on mobile where slower connections would exacerbate the problem of refreshing the page in the previous solution.
