Language Optimization

When creating a new Engine during signup, from within your dashboard, or via API, you may select a language type:

Language Optimization - Creating a Korean Engine.

Creating a Korean Engine
curl -X POST 'https://host-2376rb.api.swiftype.com/api/as/v1/engines' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer private-xxxxxxxxxxxxxxxx' \
-d '{
  "name": "national-parks-demo",
  "language": "ko"
}'

If your Engine spans multiple languages, consider using the default Universal option.

Once you have selected your language, no further configuration is required — your Engine is optimized for that language.

What does it mean to be language optimized?

Features like stemming, bigram matching, phrase matching, and typo tolerance will be fine-tuned for your chosen language.

You can select from one of the 13 language settings:

Language

Language Code, ISO 639-1 and ISO 3166-1.

"Brazilian Portuguese"

pt-br

"Chinese"

zh

"Danish""

null

The language codes adhere to a subset of the IETF RFC 5646, which coincide with ISO 639-1 and ISO 3166-1.

Once an Engine has been created with a language, it cannot be changed.

Adjusting the language requires migrating to a new Engine.
