在這個範例中，我們會使用 SQLite，因為它只用到單一檔案，而且 Python 內建支援。你可以直接複製這個範例並原樣執行。

之後，在你的正式環境應用中，你可能會想使用像 PostgreSQL 這類的資料庫伺服器。

set CGO_CFLAGS_DISALLOW to a regular expression matching arguments
that must be disallowed. In both cases the regular expression must match
a full argument: to allow -mfoo=bar, use CGO_CFLAGS_ALLOW='-mfoo.*',
not just CGO_CFLAGS_ALLOW='-mfoo'. Similarly named variables control
the allowed CPPFLAGS, CXXFLAGS, FFLAGS, and LDFLAGS.

# 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
