### Common Workflows

**Index Lifecycle:**
```java
suggester.createIndexIfNothing();      // Initial setup

        settingsBuilder.indexTimeout(fessConfig.getIndexIndexTimeout());
        settingsBuilder.indicesTimeout(fessConfig.getIndexIndicesTimeout());
        settingsBuilder.searchTimeout(fessConfig.getIndexSearchTimeout());
        settingsBuilder.setSettingsIndexName(fessConfig.getIndexDocumentSuggestIndex() + "_suggest");
