## Key Components

### Suggester (Main Entry Point)
Location: `src/main/java/org/codelibs/fess/suggest/Suggester.java`

Main operations: `suggest()`, `popularWords()`, `indexer()`, `createIndexIfNothing()`, `createNextIndex()`, `switchIndex()`, `removeDisableIndices()`

### SuggestIndexer (Indexing Engine)
Location: `src/main/java/org/codelibs/fess/suggest/index/SuggestIndexer.java`

- **Logging**: Log4j2 - `src/main/resources/log4j2.xml`
- **i18n**: All user-facing strings in `fess_label_*.properties`
- **Default Port**: 8080 (configurable via `fess.port` system property)
- **Log Location**: `target/fess-logs/` (dev), `/var/log/fess/` (prod)
- **Admin Login**: `admin/admin`
