For time-pressed customers, speed matters. Optimising the time it takes to get product listings to their customers made a tangible difference to their sales figures. Sub-second Search can do that for yours. It gets product listings to your customers fast to give you the best chance of converting their interest into real revenue.

Collections, not just products

Get customers' eye-balls onto your collections as well as specific products. If they search for "Computers", you might want to show them a collection full of computers. Sub-second Search automatically indexes all your collections and your products, to show results for both.

Configurable results

Click-and-tick configuration to control how your results look: * Configure what fields appear in search results * Exclude tagged products or collections from search results * Control the colour and font with no CSS coding required

Generous limits so you know where you are

  • Index up to 60,000 products. Works for you now and as you scale. No fuss. No traps to fall into later.
  • There's headroom for your users to conduct 60,000 monthly searches. If you get anywhere close to that then firstly your site will have exploded in popularity and secondly, we talk to you about getting even bigger.

Works with your existing theme

Users can still click through to your theme's current search results page, so you don't lose anything you've paid for already. Sub-second Search simply layers additional functionality on top to improve customer search experience, help them find the right products more quickly and return more sales for you.

On-demand product sync

Get customers searching your latest product catalogue in a single click.

Nice app to allow customers to quickly search by name for a product or category. Top stars also to the developer who responds quickly to questions via email. Good Job guys :)
