# Shopify product search for Vietnamese stores

> How IntentSea Search handles Vietnamese product names with and without diacritics, English–Vietnamese catalogues and translated Shopify stores.

Shoppers in Vietnam type the same product in many ways: **áo khoác**, **ao khoac**, **áo khoác nam** or a mix of Vietnamese and English such as **áo hoodie**. A search bar that only matches exact characters sends many of them to an empty results page.

IntentSea Search is a product search and filtering app for Shopify stores, built with Vietnamese catalogues in mind.

## What it does

- **Accent-insensitive matching.** Product titles and descriptions are indexed with accents folded, so a search typed without diacritics finds the same products as one typed with them.
- **Mixed-language catalogues.** Products with Vietnamese titles and English terms (brand names, sizes, materials) are searched together.
- **Translated stores.** The app can index translated product titles and descriptions, so shoppers search in the storefront language.
- **Vietnamese and English admin and widget.** The admin and the storefront widget are available in both languages.
- **You control the vocabulary.** Add synonym groups such as *áo khoác / jacket* and stop words, with CSV import and export.
- **Searches with no results are visible.** Analytics lists the top searches and the searches that returned nothing, so you can add a synonym or a rule where shoppers actually got stuck.

## Going further with AI

On Pro and Scale plans, an optional semantic layer adds product candidates when ordinary text search finds too few matches, and natural-language filters turn a phrase into removable filter chips. AI is never on by default: you start a control/AI trial and compare revenue per search before turning it on for everyone. See [AI search for Shopify](https://intentsea.com/guides/ai-search).
