Multilingual Search for OpenCart
One search — 100+ languages. Cross-language matching, UA/RU/PL/DE morphology without dictionaries. Built on multilingual-e5-large.
Why standard search solutions fail on UA/RU/PL/DE
Most smart-search SaaS platforms were built for the US market: English catalogs, fashion/electronics. On Ukrainian, Russian, Polish, German — morphology breaks LIKE search, and US-trained models (Klevu, Searchanise) deliver 70-80% relevance instead of 92%+.
Morphology
"Cup → Cups, Cup's" or Slavic «Чашка → Чашки, Чашці» — standard search can't connect them.
Latin/Cyrillic
"stiklokeramika" = «склокераміка» — requires cross-script matching.
Synonyms
"fridge" / "refrigerator", «штани» / «брюки» — manual dictionaries don't scale.
Cross-language
Customer on UA locale searches «сковорода» — but product is indexed only in UA as «пательня».
multilingual-e5-large-instruct: one model, 100+ languages
Open-source embedding model from Microsoft Research, trained on 100+ languages in parallel (not "English + translation"). Semantically related terms land near each other in vector space — even across languages and scripts.
📊 Benchmark: 92.7% top-3 relevance on a Ukrainian 30k SKU store (isklad.com.ua).
