### Common Workflows

**Index Lifecycle:**
```java
suggester.createIndexIfNothing();      // Initial setup
suggester.createNextIndex();            // Create new index

        final SuggestSettingsBuilder settingsBuilder = SuggestSettings.builder();
        settingsBuilder.addInitialSettings("search_engine.type", fessConfig.getFesenType());
        settingsBuilder.bulkTimeout(fessConfig.getIndexBulkTimeout());
        settingsBuilder.clusterTimeout(fessConfig.getIndexHealthTimeout());
        settingsBuilder.indexTimeout(fessConfig.getIndexIndexTimeout());
