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 into a searchable combination, which the customer can ask for however they phrase it, whatever your sector.
You never write a single regex yourself. Our rule packs — hardware, fashion, industry, automotive, electrical, plumbing, 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.
// The cascade, two levels, whatever the sector
"m8" → DIAM_M8 "jeans" → FAM_PANTALON
"stainless" → MAT_INOX "w32 l34" → TAILLE_32_34
DIAM_M8 + MAT_INOX → DIAM_M8_INOX
FAM_PANTALON + TAILLE_32_34 → JEAN_T32_34The Heurix prism: one reference, several pieces of information
One reference, several pieces of information
A product reference is never a random string of letters: it's several pieces of information compressed into one string, whatever your sector. 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.
These two diagrams run on the real Heurix engine, not a mockup: the same mechanic, applied to two different sectors. Explore the eleven rule packs or build your own.
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. Eleven 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.)
What about yours?
If your customers search by reference, dimension, or variant, the engine adapts. Tell us about your catalog.

Measured round trip
Full search round trip, network included, measured on 11 September 2026 on the public demo (2,821 and 1,500 products): 120 calls, median 46 ms, from a machine 11 ms from the server. The engine itself accounts for about 30 ms of that at the median, the rest is network. Further from the server, expect more.
2 typos
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.
