### Common Workflows

**Index Lifecycle:**
```java
suggester.createIndexIfNothing();      // Initial setup
suggester.createNextIndex();            // Create new index
// ... indexing operations ...
suggester.switchIndex();                // Switch to new index
suggester.removeDisableIndices();       // Cleanup old indices
```

**Async Operations:**
```java
suggester.suggest()

                int index = userInfo.indexOf(':');
                user = index != -1 ? userInfo.substring(0, index) : userInfo;
                if (index != -1) {
                    password = userInfo.substring(index + 1);
                }
                index = user.indexOf('\\');
                if (index == -1) {
                    index = user.indexOf('/');
                }

                client.admin().indices().prepareCreate(TEST_INDEX).setSettings(indexSettings).execute().actionGet();

        assertTrue(createIndexResponse.isAcknowledged());

        // Create suggest settings index
        Settings suggestIndexSettings = Settings.builder().put("number_of_shards", 1).put("number_of_replicas", 0).build();

  }

  @Override
  int indexOf(@Nullable Object target) {
    int index = forward.indexOf(target);
    if (index == -1) {
      return index;
    } else {
      return size() - 1 - index;
    }
  }

  @Override
