The native engine indexes — it doesn't understand
The one shipped with your CMS reads the catalog, but it ignores typos, your business synonyms, and the order your products should appear in.
The engine
A proprietary search and indexing engine.
Heurix isn't a layer on top of Algolia or Elasticsearch: it's our own engine, built in France, specialized for technical catalogs. Where generalist engines compare characters, Heurix reads the structure of your references.
The demo at the top of this page runs on this exact engine — the numbers alongside it are measured, not promised.

A concrete competitive edge: understanding references, not just words
Rules that read structure
Heurix recognizes the components of a reference — family, dimension, material, standard — and turns them into usable attributes.
Then combines them into concepts
A second layer assembles these attributes: M8 diameter + stainless material becomes a searchable combination, which the customer can ask for however they phrase it.
⚡ You never write a single regex yourself. Our rule packs — hardware, fashion, industry, books, electronics, wine & spirits, finance & accounting — are pre-configured and activate when you pick your industry, at indexing time. A term specific to your catalog that we don't cover yet? Add your own Custom Rule from the console, simply describing what it should recognize.
Hardware industry example: searching "M8x20 stainless"
The Heurix prism: one reference, several pieces of information
One reference, several pieces of information
M8 x 20 — Stainless A2 isn't a string of letters: it's a diameter, a length, and a material compressed into one string. Most engines compare characters and fail as soon as the format changes.
Heurix works like a prism: the reference goes in as a single beam, comes out decomposed into searchable attributes — and your customer finds it by any fragment, in any order, with or without a typo.
⚡ This diagram runs on the real Heurix engine, not a mockup — it's exactly the logic that processes your catalog from the moment you index it.
The industries where this approach changes the most
The larger a catalog or content base, the bigger the gain from well-tuned search — because native search fails exactly where precision matters most. Seven of these industries already have a dedicated rule pack, ready to use; the others are covered with Custom Rules in a few minutes, no regex required.
Fashion & retail
Compound sizes (W32/L34), colorways, materials, variants — and customers who type fast, with typos.
Dedicated pack: fashion
Hardware & tools
Tens of thousands of references, standardized product codes (DIN, ISO), the need to filter by dimension, material, compatibility.
Dedicated pack: hardware
Spare parts & industry
Search by manufacturer reference or equivalence, tolerance for multiple code formats depending on the supplier.
Dedicated pack: industry
Books & publishing
ISBN, editions, formats, collections: the same title exists in dozens of versions — the demo on this page proves it.
Dedicated pack: books
Electrical & electronics
Precise technical specs (voltage, amperage, standards), catalogs that evolve continuously.
Dedicated pack: electronics
Trade & construction equipment
High volumes, professional buyers who search by exact reference more than by descriptive keyword.
Wine & spirits
Vintages, estates, appellations, formats (375ml, magnum): references where every digit matters.
Dedicated pack: wine
Content, blog & documentation
Articles, FAQs, knowledge bases: the same typo tolerance that finds a product reference finds a poorly-worded question. (Try Ctrl+K on this page.)

Tolerated per word
"pul rond red neck" still finds red crewneck pullovers. Just one on references — change a single digit, and it's a different product.
