# Adding a New Language to Fess

This guide explains how to add internationalization (i18n) support for a new language in Fess.

## Overview

Fess uses a two-tier language support system:

1. **Full UI Translation** (13 languages): Complete user interface translation with label and message files
2. **Search/Analysis Support** (40+ languages): Language-specific text analysis for search indexing

- ACCEPTED on 2025-08-06

## Context

Our codebase uses `null` extensively to represent an absence of value or optionality of the argument.
We utilize nullness annotations in Java code and somewhat rely on IDE warnings to guide us.
However, the Java code we have is not fully annotated, which causes several consequences:
* IDE warnings can be misleading
* Redundant null checks may increase binary size, hurt performance, and increase cognitive load for readers
