The Shopify search that understands your references
Test it first on your own site: search the same reference in three forms — M8x20, M8 x 20, M8-20. If the three result counts differ, this page is for you.
What native search can't do
Narrow typo tolerance
According to its documentation, Shopify's native search accepts one wrong letter or two swapped letters, only if the first four letters are right, and only in the title, product type, variant title and vendor. “wahser”, whose swap falls inside the first four letters, is outside that scope. On a technical catalog where people type references on a keyboard, that limit matters.
Large catalogs
According to the Search & Discovery documentation, a collection with more than 5,000 products doesn't display filters, and a store can have at most 25 filters. That's exactly the size where a real engine becomes necessary.
Technical references
Its documentation says search matches complete words, and that part of a code is found only when the code contains hyphens: “abc1888” must be typed in full.
Where the Shopify integration stands
An app, in review at Shopify
Heurix Search is a Shopify app. It imports your catalog, keeps it current each time a product is edited, and adds to your theme a search bar that queries Heurix. We submitted it to App Store review on September 13, 2026. To date, Shopify has neither approved nor rejected it.
Where it runs
On four stores: our test stores and the Shopify reviewer's. None of them is a merchant's store. Until review concludes, the app does not install from the App Store, and we know neither when review will conclude nor which way.
What it replaces
The bar shows Heurix results as you type. "See all results" leads to your theme's search page, which remains Shopify's.
The API guide, without the app
The guide goes through a serverless function that holds your key and acts as a relay: it is never readable by visitors. That guide has not been proven on a real store. Write to us rather than following an approximate recipe.
If you are counting on us a month from now: if review succeeds, the app will install from the App Store; if it is rejected, or has not concluded, the route remains the API and its guide. Today, PrestaShop has a paid module sold on PrestaShop Addons; WooCommerce, a plugin published on wordpress.org.
Corrected on September 19, 2026. Since September 6, this page said we had not yet connected Heurix to any Shopify store, and that there was neither a theme extension nor an app. That was true the day it was written; the app was installed on our test stores in the days that followed, and the page did not say so.
