Handles all indexing operations, content parsing, and word management (bad words, elevate words).

### SuggestSettings (Configuration)
Location: `src/main/java/org/codelibs/fess/suggest/settings/SuggestSettings.java`

Manages configuration stored in OpenSearch: analyzers, bad words, elevate words, timeouts.

 * and elevate word settings.</p>
 *
 * <p>It also includes a nested TimeoutSettings class to manage various timeout configurations.</p>
