## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

1. **Query parameter**: `?browser_lang=[locale]` (highest priority)
2. **Browser header**: `Accept-Language` header
3. **Fallback**: English (from `fess_label.properties` and `fess_message.properties`)

### Document Language Detection

During crawling and indexing, Fess:
